try standard HIMEM.SYS with /MACHINE:AT switch...

i use one only "boot manager" — PART, and only in minimal and stupid variant — one sector in MBR. this enough for select bw Win98, XP, 10 or Linux on same disk. 3-4 boot options per disk, switch to next disk, no PLOPS, no GRUBS, no CRABS, no PROBLEMS...

you mean DMA? yes, these exist ONE that driver for relative modern machines (as i think, begin at P2 era) — UDMA/XDMA/UIDE/UHDD/XIDE/XHDD.SYS series, which also is disk cache. http://optimizr.dyndns.org/dos/drivers.html also i remember some "accelerated" drivers for older hardware (MSDOS/Win31 era)... but they is not generic, and in general useless... ordinal SMARTDRV give better effect. last, all used me AHCI hardware and BIOS do HDD access fast enough to not use any other drivers or caches (use SMARTDRV, if you need speed-up random access for find files at all disk). and REMEMBER: SMARTDRV have BUG, affecting on PARTITIONS bigger than 128 GiB (128 *1024 *1024 *1024 bytes) sized!

for what? if you talk about CD/DVD drive — yes, there is VIDECDD.SYS for Legacy IDE (ie "true ISA IDE cntrls at ports below 400h"), UIDE/UDVD/XIDE/XDVD.SYS series for Native SATA mode (aka "non-legacy PCI IDE at ports above 400h"), and AHCI.SYS from Rloew, for AHCI mode.

or we have just buggy/bad code is IDE cntrl BIOS add-on or main bios.

are u try w/o JEMM* ? JEMM* is not compatible with 9x, even if DOS 7 normally work. as i see on google, Thinkpad T410 is too MODERN machine for 9x: - it is ACPI machine with too new ACPI standart version for 9x = many potencial problems with PnP and PCI subsystem of 9x. - have too many RAM, cause many problems, which not fully solved with PATCHMEM (possible bad memory layout). - use SATA or even AHCI mode for disk = need Rloew SATA patches, and AHCI driver (and latest Sweetlow patches for both). - have EHCI mode USB cntrs only = need USB20 stack from ME/2K/XP (and patches by Sweetlow). - have external graphical chip Nvidia Quadro, and there no drivers for 9x, except VBEMP. and also it is NOTEBOOK, what mean possibility other problems, often completely unexpected...

1) jemm* never work with 9x. 2) need full stack Rloew patches.

i mean "without ANY potentially intervening layers between hardware and windows". GRUB does intercept some interrupts and modify some system tables during his work.

are u try install w/o any grabs/crabs/etc?

on my first expirience with 1155 i have long time with 98 install failure, until try ban acpi fully...

try setup /p i

i found likely problem with my experiments on "old pc simulators", when used scsi. not sure, that here is allowed to attach or link "heavy modded io.sys file", but... i can send it you for test to private, if you interested. or, as variant, try install ME.

what disk cntrs mode is selected in BIOS? try set it to any non-RAID option. try disable in BIOS all disk cntrs and other devices, except really needed for boot, which possible.

why even use dpmi for such simple app?

no, no, no! hybrid sys+exe is not just concatenation. when loading exe file via DEVICE= command, DOS wiill skip exe header only, not all body of exe file. u need rewrite source for it.

why dont make combo version as one exe file?

you need run fix before emm...

me also tested your patch with other 9x system in VMWare, now with installed native vm videodriver. it work good, without these nightmares as with VGA. but console now work exactly on 1070... ie: 1) i run some console app (Norton Commander), as result get pic 1 (empty windowed or full screen with blinking cursor prompt line of NC); 2) if it was windowed, then need go to fs mode via Alt+Enter hotkey (pic 2); 3) after this me press Alt+F9 hotkey inside NC (change vidoe lines count 25/50), and now i get normal look (3); 4) now i can press Alt+Enter hotkey again (4), press Alt+F9 to change window lines number (5), but... 5) if now press Alt+Enter hotkey again (6), it look enough strange, possible it related with my localization utility (CLARUS), i will check it later; 6) remained in fs, press Alt+F9 hotkey again — now it look nice... (7) thank for your work! 1 https://picabox.ru/pictures/2025/01/08/16/39/1535482378.png 2 https://picabox.ru/pictures/2025/01/08/16/39/1535482183.png 3 https://picabox.ru/pictures/2025/01/08/16/39/1535482222.png 4 https://picabox.ru/pictures/2025/01/08/16/39/1535482261.png 5 https://picabox.ru/pictures/2025/01/08/16/39/1535482300.png 6 https://picabox.ru/pictures/2025/01/08/16/39/1535482339.png 7 https://picabox.ru/pictures/2025/01/08/16/39/1535482144.png

hi! thanks! it really WORK on hardware GTX1070! i have tested with VBEMP and VGA drivers, both in normal and safe mode (dirty non-US Windows, sorry), and it work even with console, and even in fullscreen mode! not ideally, and console is unstable, but it WORK. look to attached images. unfortunatelly, this patch fully breaks standard 9x VGA driver in VMWare (pure 98SE US Retail w/o any other patches)... look to images on links. https://picabox.ru/pictures/2025/01/06/22/52/1534923391.png https://picabox.ru/pictures/2025/01/06/22/52/1534923313.png https://picabox.ru/pictures/2025/01/06/22/52/1534923196.png

sorry, this bootlog is for safe mode or normal mode?

click f8 on reboot, do select step-by-step boot (include windows booting), and check, which driver cause problem. after this, try sbs boot again with manual skipping problem driver. if no success, then boot with logging to bootlog.txt, and attach here files bootlog.txt and bootlog.prv.

uh, nice, nice! so where i can download ur patch? and, if possible, me want know, which bytes need to patch manually, especially for DOS. (i dont like in-memory patches, as least, for legacy systems w/o any protections and cryptos...)

hi! yes, me still using 1070 and i'm interested in your patch. i solved that VDD bug back in 2021, I've been booting into GUI successfully since then, but i forgot to report it here. the problem was that VDD was trying to explicitly set the EGA video mode, even if this mode was not used in any way afterwards. unfortunately, right after resolving this problem, there appears the second one: a console (DOS box) doesn't run, giving the same error address C000:FFFF on start rendering own window. I see FAR on your picture. does it (as well as other DOS boxes) work normally with your patch? if so — i am very interested!

get it out of your head, it doesn't work.
