Drivers by Jack Ellis

This collection includes CC, RDisk, RDiskOn, UDVD2, UHDD, UIDE, and XMgr. This is a ZIP archive; individual package files are also available.

drivers-2021-10-30.zip Size: 147.5 kB Released: 2021-10-30 MD5: `553BEF77C29DB952BA4F2E8B0955054A` Downloads: -	UHDD uses mostly caching logic even for noncached work, saving 650+ bytes on disk! UHDD.SYS is now less than 5K, suitable even for crowded 'boot diskettes' etc. All UHDD features, switches and cache speeds do remain UNCHANGED! [The /B noncached UHDD, not often used, now uses ~ 300 bytes of additional RAM compared to the previous version].
drivers-2020-07-14a.zip Size: 154.9 kB Released: 2020-04-29 MD5: `3CB9995D091F0280745E3D5ECF03105E` Downloads: -	UHDD's /O switch now enables DMA/Caching Overlap! It and Read-Ahead allow UHDD up to 20% faster caching speed than UIDE on V6.22 MS-DOS and similar speed gains for FreeDOS. See the comments about UHDD /O in Section 5, below. Due to Overlap, UHDD now runs up to 20 BIOS disks (was 22). UIDE now updated with all UHDD updates and 'bug fixes' from 15-Feb-2019 onward. It now offers 10-MB and all 20-MB+ cache sizes for old small-memory systems. UHDD fixed to run 9 controllers and 'LBA48' disks (> 128-GB) correctly. It now does Read-Ahead with all 10-MB+ caches. See the driver .ASM source files for full notes on these changes.
drivers-2020-04-15.zip Size: 157.9 kB Released: 2020-04-15 MD5: `4EE70D2099B155719EB5FA72C673C114` Downloads: -	XMGR updated from the 5-Mar-2015 version as follows: The 'I-O Catcher' now handles a maximum of 16 BIOS hard disks. Real-mode and /Z protected-mode XMS move sections are 4K bytes for faster speed (was 2K). The /B 'boot' option now permits /N32 to set 32 XMS 'Handles', saving 160 low-memory bytes versus the 48 'Handles' default. The 80386 'errata' commands recommended by Ninho are included. The HIMEM de-facto standard driver name of 'XMSXXXX0' is used.

ListPCI

ListPCI is a PCI device listing utility which scans the PCI bus of the system on which its running and displays data on all PCI devices it finds. It provides more verbose data than other comparable applications and is more flexible in its command line options. Using these, you may filter the devices reported to only those of a specified vendor ID or of a specified class. ListPCI can also return the number of matching devices in the DOS system variable ERRORLEVEL, making it easy to integrate into batch scripts.
Note: This application requires a 386 or higher CPU.

ListPCI 1.02.zip Size: 85.0 kB Released: 2021-07-11 MD5: `D2CA9DA733ACA0B9392722C1B83596FA` Downloads: -	Added email address to application banner.
ListPCI 1.01.zip Size: 84.9 kB Released: 2021-07-09 MD5: `08A14DB07B6D2E3C7D6F50513D14676C` Downloads: -	Improved string handling, added readme and scripts to package for building under DOS and Linux.
ListPCI 1.00.zip Size: 83.2 kB Released: 2021-07-01 MD5: `0F68D52928F377DB92FA266D7B34ECBF` Downloads: -	Initial release.

ListVESA

ListVESA is a utility to report which VESA video modes are supported by the system's hardware. You can use command line options to tailor information listed to one specific mode, modes supporting a specific color bit depth, modes supporting linear frame buffer, or simply general information on the video adapter itself or a table summarizing available modes with no detailed screen data.
Note: This application requires a 386 or higher CPU.

ListVESA 1.11.zip Size: 21.0 kB Released: 2023-05-02 MD5: `AA9D8CBEC8A02C3811F2D0AFE810CCD5` Downloads: -	ERRORLEVELs are now returned. Fixed a bug where reserved set bits in the Mode Attributes weren't caught unless all three were set. Fixed a bug which printed a spurious blank line if the "Window B Segment" field contained an address. Previously, ListVESA assumed a minimum of one byte per pixel, even for modes with color depths below this value, e.g. 4 bit color. This assumption has been eliminated, and the algorithm now used is much more accurate. Removed the 'Mode Summary' text as it's a bit obvious in the output what the user is being shown. No need to label it explicitly. Tidied up the code with some DEFINEs. Window statistics are now grouped together; previously the segment value and the attributes were listed separately in keeping with the order in which the fields appeared within the tVESAModeInfo struct.
ListVESA 1.10.zip Size: 20.0 kB Released: 2023-04-29 MD5: `9C571CC1B31A5E8038F33072097D06AC` Downloads: -	Fixed a minor bug involving the mode count when using the /A switch. Improved (once again) the layout of trailing blank lines after the various sections of information which ListVESA dumps. Optimized a tiny bit of assembly code. Removed a bit of leftover debug code.
ListVESA 1.09.zip Size: 20.0 kB Released: 2023-04-29 MD5: `1ED9AD9CECBD741BF467FCEE80AFC2DA` Downloads: -	A summary is no longer displayed when using /M. Why do you need to summarize a single mode? :) Added message for modes which don't exist on the system. Slightly updated the description for the /D switch. Using /M now implies /V.
ListVESA 1.08.zip Size: 19.7 kB Released: 2023-04-29 MD5: `61C7E6150AF85D4D65B9B2D5ED4F40FE` Downloads: -	Added warnings for the user if the BIOS has returned illogical information for a given mode; a message in the detailed list, and an exclamation point beside the entry in the summary table. Updated the application description to include the summary table feature.
ListVESA 1.07.zip Size: 19.5 kB Released: 2023-04-29 MD5: `E6A2789A7D2CADF8AAFF0F63A4FC7771` Downloads: -	Fixed a bug resulting from some inconsistent previous optimizations which broke functionality of the /M switch.
ListVESA 1.06.zip Size: 19.4 kB Released: 2023-04-28 MD5: `B6A80C734C228A53915B683DFCFD6319` Downloads: -	Fixed a bug in the previous version which prevented the detailed list from being generated. The source code included with that version is fine, but the binary must've ended up with some debug code in it which I had in place to help narrow down a separate issue. Oops! Fixed a typo in the readme file. Spoiler alert: 'scren' isn't a word. At least not in English! ^_^ Fixed the two compiler warnings. It's amazing what properly typecasting a pointer can do! Improved switch handling logic. Improved the layout of trailing blank lines after the various sections of information which ListVESA dumps. Optimized code; redundant bits were moved to a separate function, VESAModeInfoGet(). Tweaked the 'incompetent VBIOS manufacturer' message a bit to flow better and take up less space in the binary.
ListVESA 1.05.zip Size: 18.9 kB Released: 2023-04-27 MD5: `55E88FB52208BEE80B9A0E288CC4D9FE` Downloads: -	Increased scrutiny of video modes reported by the video BIOS so that illogical modes can be skipped, and added /V switch to print all screen modes, no matter how illogical they may seem.
ListVESA 1.04.zip Size: 18.1 kB Released: 2023-04-26 MD5: `AC620FF49B9FE90EEE0EC5D8A6D9EDB9` Downloads: -	Added the 'divide by zero' bug fix back in because... crazy video hardware manufacturers. sigh
ListVESA 1.03.zip Size: 18.0 kB Released: 2023-04-25 MD5: `3063886ABCA76C5826B9AAF048AAD845` Downloads: -	Added a 'summary' mode - with accompanying /S switch - to be a bit more terse if desired. Added dates to the changelog. Woot woot! Added more detailed output for the Memory Model field instead of simply printing the type code. Changed Frame Size calculation to 'charsWide x charsHigh' for text modes. If someone out there encounters a text mode in the wild, I'd love to know how ListVESA does in reporting it! Fixed a bug where AX was not checked to be 0x004F after a mode info call. This fixes the spurious output of modes with all null values as found in the (somewhat crazy) data tables of some video hardware. This allows the previous 'divide by zero' bug fix to be rolled back, as this fix supersedes it. Thanks Jerome! Fixed a bug where program help was included in the binary but no command line option would show it. Wow lol Hexadecimal numbers are now uppercase
ListVESA 1.02.zip Size: 16.7 kB Released: 2023-04-24 MD5: `0B37BACE93C31E6792088DEF7B282B7E` Downloads: -	Fixed 'divide by zero' bug which could occur with certain VESA chipset manufacturers who leave certain mandatory fields blank. Thanks to Jerome Shidel for the bug report!
ListVESA 1.01.zip Size: 16.5 kB Released: 2021-07-11 MD5: `453DBF3ACEEA8242F4B46BAD3B22C6C1` Downloads: -	Added column and row figures for character widths and heights, added email address to application banner.
ListVESA 1.00.zip Size: 16.4 kB Released: 2021-07-10 MD5: `FD40BC28E609C93C34C47DB2616D3C74` Downloads: -	Initial release.

Size: 383.3 kB
Released: 2025-09-02
MD5: AF5C8A2351CBE6743F0D01948FFE96B9
Downloads: - A schematic mirroring the one officially released by PJRC, but created in KiCad to serve as a handy jumping-off point for creating a custom Teensy 4.1 board. It features a custom symbol for the i.MX RT1062 processor which lists all its pins, not only the ones used in the Teensy 4.1. Names have been used for all test points, the names of the chips have been added/enhanced (e.g. 'DP83825 Ethernet Interface' instead of simply 'DP83825' and the name for pin E6 has been corrected per the iMXRT datasheet. All component numbers are kept identical for consistency reasons.

Kernel Series 1.xx

version1.40.zip Size: 144.1 kB Released: 2007-12-16 MD5: `5B67D6032D97E890D9E93EE9923DD796` Downloads: -	Merged ExecInstruction() with Main() for further speed increases Trimmed code for unsupported instructions from ExecInstruction() to clean up the source Overhauled code execution core algorithm for speed, yielding major performance gains; individual instructions still need optimized Added kint 0x33 (set thread priority) Added kint 0x32 (set thread pause state) Added 'priority' to the threadData type to allow different threads to have more CPU time than others (e.g., the kernel infinite loop is set to lowest, and all other launched threads are set to the highest, but a thread can set its own priority if it doesn't require the highest speed setting) The kernel now informs the user of the status change of a thread when 'thread x pause' is used
version1.35.zip Size: 128.3 kB Released: 2007-01-20 MD5: `0BC6FCFE6B9978A1B203EC1D7A1CE9A4` Downloads: -	Optimized some portions of code for speed Added simple debugger which displays the register contents as the program executes Fixed bugs in kint 0x09 involving cursor positioning Fixed cursor relocation bug in kint 0x03 Eliminated need for the CLIST and DAREA resources, apps may now only have one 32K block for code and data, the DS register does not get set upon app load, and the mov family of instructions all access exactly the address they're told, instead of adding the value of ds to the address first Fixed bugs in kint function 0x18 Added kint 0x31(draw line)
version1.34.zip Size: 125.4 kB Released: 2006-11-01 MD5: `9A73FE9AC8D4AE387BD06C26E60C6020` Downloads: -	To reduce source code size and segmentation problems the built-in debugger has been removed The command prompt now checks to see if drive c is available before assuming it is, and makes the first drive available as the default drive if c: isn't there Fixed a bug where the drives command would display incorrect drive information for CD-ROM drives under plain DOS, not when being run from within Windows Eliminated run command, just typing the program's name will run it as in DOS; if you type only the program name (e.g. 'program' not 'program.exe') the kernel will first look for a program of that title in the following extension order: .pco, .bat, .com, and .exe Improved consistency of output of the mem command so far as handles allocated and block sizes; output used to differ widely depending on which underlying xms driver is being used Certain essential system threads are now able to be designated as 'locked,' meaning they cannot be terminated; currently only thread 0 uses this, and that's probably how it should stay Fixed annoying cursor relocation bug after dismissing an error box by pressing ESC Fixed memory leak when using the restart command, due to the kernel not terminating all running threads before resetting itself... trying to restart the kernel now will generate an error if any threads are running Got rid of the annoying prompt 'Press any key to begin the program.' when launching DOS apps Fixed minor annoyances in the appearance of the text as a Exelyx app loads Improved error handling and thread stability issues Replaced the 'Press DEL to access the system menu.' line with 'Press DEL to terminate this thread.' in error boxes to eliminate having to do more error checking from having the command prompt running over top itself Modified kernel startup error handling to include XMS setup also before switching over to the main error handler Fixed text appearance of thread command output, no more wrapping lines Eliminated two separate thread name fields (public and private) so threads can now only have one universal name Fixed startup procedure so that if a file is specified it gets run, or if no file is specified on the command line the kernel goes straight to the command prompt Fixed a bug concerning remnants of the old Exelyx-style lfn support; the kernel no longer tries to see if a folder or file contains a Exelyx filename Fixed a bug in the Exelyx app loading routine which would leave a thread incompletely set up if an error occurred while attempting to load the app's CODE resources Fixed a bug in how the kernel detects the amount of XMS installed and XMS free; the kernel has always used all installed memory, but would just report the wrong numbers for how much was there, now the correct numbers are shown Made minor changes to the XMS section of the output of the mem command Added /nhp switch to disable handle probing which causes problems under windows Fixed a bug in the xms release command that would let handles which are in use by an app be terminated The dir command now recognizes invalid switches Added /s switch to the dir command Added separate file and folder counters to the dir command's output, in addition to the usual item count Fixed output of date command (used to be an error with 1st, 2nd, 3rd, etc...) Fixed output of drives command, line wrapping / spacing bug with mapped drives Fixed bug in copy command that puts the system in an infinite loop if an error occurs while copying Fixed bug where every directory created with a long filename is made lowercase Fixed bug in mem command that caused overflow errors Added 'restart' command Fixed drive label bug where the label for drive C would appear as the label for every drive Enabled asterisk wildcard in 'dir' for file filtering Added /w switch to the dir command Added support to 'dir' for listing directories other than the one you're currently in Modified drives command to include displaying drive labels Added /a switch to the dir command Increased stability of copy command when used on non-lfn drives Added commands: copy, credits, date, drives, eject, info, label, login, logout, make, pause, ren, time, type Enhanced ver command Fixed a bug where commands typed with leading spaces are not recognized Fixed the program launch bug where when typing the name of a program to run it, the kernel displays 'The command or filename is not recognized.' regardless of whether or not the program actually existed. also, if the program did not exist, an error dialog used to appear in addition to the message Md/mkdir now work properly Dir command works Rd/rmdir gives no errors Fixed a bug with the cd command where it would change to a directory that doesn't exist if you type an 8 character or longer dir name with extra letters, just so the first 8 match The thread command now works properly when used with 'stop' Commands typed in mixed case now will execute Run command added
version1.33.zip Size: 135.8 kB Released: 2006-05-01 MD5: `C3AF1221C3B1FB744B013BC8FF3964A7` Downloads: -	Added built-in command prompt interface to replace limited console menu system Eliminated Exelyx-style LFN support in favor of the Windows style... why complicate things by having three standards for filenames when we could have only two? :) Temporarily removed KINT 0x27, 0x26, 0x25, 0x24 and 0x23; they need rewritten to use Windows lfn Modified KINTs 0x0C and 0x17 to not use Exelyx-style lfn's; need to add Windows lfn support though

Y2KPatch.zip
Size: 4.8 kB
Released: 1999
MD5: D78E7E0BF6CADD45BDCFBC63F3EA52F5
Downloads: - Ah, yes, the dreaded Y2K bug! Amidst the grandiose predictions of 'experts' that application programs the globe over would collectively perform a lemming-style address jump to their deaths when their RTC overflowed to zero, I did what I always do: wrote a little code to probe, test, and solve. The result is a collection of four BASIC source files comprising an installer, uninstaller, a test to see if the computer in question is even affected by the Y2K bug to begin with, and a patch which fixes the issue if it is. Not an issue nowadays, granted, but back then it was awesome to see this code enable some pretty ancient MS-DOS systems suddenly have the correct date when before they could not manage to do so.

GETWORD.BAS
Size: 1.8 kB
Released: 1999
MD5: FB969BD9880030492ADA999DAB4A6D0B
Downloads: - One of the most useful pieces of code I've ever written, it's found use in numerous situations. Back when I wrote it, the various BASICs I used (BASICA, QBASIC, VBDOS, PowerBASIC) had no function to split a string based on a certain character... so I made my own. Mind you, this was long before modern languages like JavaScript shipped with their own method for doing so. Even now it proves useful as it splits strings differently than the built-in offerings of JavaScript.
