  1. I got report that current patched driver now works with 256MB VRAM card so anyone interested to try with 512MB?

    XomPie

    Hi, I know this is an old thread and Xompie was probably abandoned but I found it quite recently and finally had time to play with it because I see some advantages in patching individual apps instead messing whole system. So I installed Xompie (the last version from Github) on my up to date XP SP3 + Posready updates with fresh install of MSVC++ 2013 & 2015 redist. Problem is that any program I patched didn't work then (those supposed to work like Adobe DNG converter that was mentioned by author). LDD finds all dependent DLLs after patching in my windows\system32 but the patched progra
  3. The previous version of patched driver caused crash (memory protection BSOD). This was probably due to Dword at 144h that I left untouched but it seems it may be code size so I had to adjust it. Now it should go a bit step further, file reuploaded: http://rayer.g6.cz/1tmp/7772mod.vxd
  4. No, 77.72 will not work with 7900/7600, AFAIK only 7800 works (G70 core, others are G71/73 - too new).
  5. BTW Windows XP can be installed with uniprocessor kernel so then you better compare singlecore performance in w98 vs XP. Also you can just swap your CPU to an older singlecore one to see if SMP cause so high gain in XP - I doubt so. Newer videobios would be good to try but aslo I doubt it help, it usually can fix/break some VESA features... I flashed a lot of VGAs but never it had significant performance difference (except bioses with different clock settings). In the distant past I had a big headaches with AGP on non-intel chipset boards. They were cheaper and I had not much money a
  6. As you know, R.Loew made nvidia videomem size patch for >256MB cards, that modifies NVCORE.VXD of 82.69 drivers. A friend of mine asked me if the patch can be backported to 77.72 drivers because he claims the newer drivers renders artefacts in some games on his GF7800. I never had GF7800, only GF7600 and GF7900 and had no problems with 82.69 drivers (except shutdown problem). So I tried to look what the patch changed on NVCORE.VXD ver 82.69. I found 3 code hooks by JMP/CALL that referenced a piece of new code added in a caveat near EOF. I tried to find similar code in ver 77.72, patched it,
  7. Cool, is there plan also for extender of userspace API (some kernelex ressurection for NT with e.g. a help of WINE codebase)? If I remember I saw some attempts but nothing alive...
  8. Hi, is there some newer unofficial build of MPC-HC player than 1.7.13 (2017) or LAVfilters newer than 0.70.2? I found an (seems to be good enough) alternative PotPlayer: http://potplayer.daum.net/ It still supports XP in 2020 and seems to be often updated. I also reccomend to install Strongene Lentoid HEVC Decoder http://www.strongene.com/en/hevc/hevcProduct.jsp for those with old VGAs without HW H265 decoder. This codec is ~2x faster on CPU than LAVfilters/FFDshow! It should support also OpenCL decoding on GPU but probably only on ATI/AMD cards didn't work on my GTX 6
  9. Hi, did someone try to compile some recent 7zip for Win9x? I tested that official ver 18.06 is working with KernelEx but only the commandline tool 7z.exe but not the GUI. GUI version 16.04 can run with KEX but only some parts are working, eg. extract files from archive but cannot create new archive.
  10. On P31/ICH7 chipset the IDE legacy mode works just fine, I didn't use AHCI there. I installed the INF files after Win98, no slipstream. In device manager I had proper ide controller working in DMA mode. I installed nUSB 3.3c The only device I had disabled in BIOS was onboard intel HD audio. I had some issuses with SB Audigy 2 and sound crackling (all OS I had installed) so I replaced it by Audigy 1 and it works fine. Used Creative driver 3.0.0.18 (according to INF file) I was lucky to have real floppy. it's sometimes usefull so didn't need to hunt phantom :) The s
  11. Aha, I just found that Borland C supported something called a precompiled headers. This should generate some extra file from *.h files that is then combined with *.c files via specific BCC command line option. It should help to speed up compilation. Maybe he used some historic slow PC for building DOS tools? If you find some free time please upload packed compiler, maybe he had placed headers and compiling batch/makefiles there. I don't hurry with it...
  12. Many thanks for sharing with us. It may look he used some Borland C, I'll try to rebuild. I wonder he used a lot of inline asm code and there's no any include statement, even for <stdio.h>. Maybe he didn't even use stdlib. If I cannot rebuild it will be still usable to study the code how DMA IDE commans calls works. UPDATE: Well, the code looks a bit cryptic but it compiles with BC++ 4.52, just to ignore tons of warnings about missing prototypes. This can be fixed easily creating a header file...
  13. Thanks for permission of distributing the patches. In a case that even source codes become freely available I would be interested in extending the TRIM tool support also on FAT16 FS. I started to write my own TRIM years ago with partial success but after discarding the first block (I checked that it was really blanked) my IDE controller left in some error state with busy LED on and I didn't manage to solve this problem. Nobody can help me with this because not much people knowledges goes so deep and want to share it. RL made it working...
  14. That's a pitty he disappeared with his deep knowledges of this old systems. I remember we discused various HW problems and he helped me with RTL8111B under Win98 via his free SPLIT8MB.EXE tool. R.I.P.
  15. I finally found the problem, I had corrupted the file WINDOWS\INF\UNREGMP2.EXE I just replaced this one file in my current XP and installation of drivers was OK, no more explorer crash...
