I did more tests today.... apparently the ram chips were not to blame because Checkit fails with every ram I tried... I even tried the 2nd 386DX mobo and had the same failure. I assume that checkit it does not like DOS7.1 ... The AITD gfx corruption was because I had 0WS enabled in the VGA VRAM. I …

yes it is slow as I see now... if you look on the BIOS screen I posted above the defaults that I loaded have 2 W.S. for DRAM... I'll change it since it is most likely the culprit ... I have installed 8x1MB 70ns simms IIRC I was running Alone In The Dark and got a hard lock when the "chicken monster" …

I made some "heavy usage" this evening... LOL Transfered via mTCP ftp server ~1.03GB/10.200+ files with about 390kb/sec (not to shabby!) and did the mandatory Speedsys tests: http://i43.tinypic.com/f0e16b.jpg I am happy with the setup, a 20GB silent HDD (all smaller ones were too noisy for my taste) …

@elianda Try and run Turrican II for example with EMS. No go. Also there is a respectable number of other games as well that don't like v386 mode. I am sure you know many as well. And the most important factor of all is personal preferences. LOL I just don't like EMM386 or whatever EMS handler …

But loading EMM386 puts the cpu in v386 mode whether it allocates ram as EMS or not, so it's a no go. I will stick to using TLB for now until I notice an error or something ... I'll aslo enable the Video Bios shadowing... I assume the cached/INTO-486 options refer to the possibility of said shadowed …

I see, thanks for the F segment explanation... I was not clear enough on the UMB driver, I need one other than EMM386 , so that UMB works in XMS-only. The Last Byte works perfect but that shareware delay is bugging me. It seems strange that URAM needs a 486, IIRC it states in readme that it works in …

jwt27 thanks for the info, I have downloaded the driver pack you mention... I thought that NE2000 was a standard (like soundblaster for a rough example) to make all various nics of the time more-or-less compatible... I'll give 3C503.COM a go :) edit: by looking at the silkscreening of the genius …

thanks CapnCrunch53 :) personally I don't really like it LOL but it will do... I should have soldered a different and smaller wire but got bored and just went with it... the mobo did have an external battery header but I prefer to have it onboard as the modification is a simple one, a diode and a …

nice story! Mine was in 1991 with and IBM PS1/pro (386sx20/2MB/VGA/80B HDD) , there was some sort of DOS launcher menu that launched "boring" programs like DOS word processor or MS works or win3... I crapped my pants when I found out that pressing RIGHT the menu changed to the GAMES section! I …
