AWE cards come with extra PnP resources which were not (yet) fully covered due to my lack of understanding. Maybe this explains the missing MIDI music in games (although having tried to add E620 to environment var like: set BLASTER=A220 I5 D1 H1 P330 E620 T2). I've uploaded the source code here with …

Great thanks, your utility works fine for me! :) Glad to here about it! Works with CT4170 on my non-PNP 486 motherboard aswell. Thank you! Glad to know it too. However, on a non-PnP 486 (386 +) system, the official utilities (CTCM, DIAGNOSE) are available and should be better choices. Would u like …

In my 286 all the PNP utility did was hard lock the system. The same happened to me when I tried that on two different 286 boards, and on a friend's 286 pc. I managed to have SB ViBRA16X (CT4170) working in my XT box. Since ctcm.exe doesn't work on 286 or before, I actually coded an old school …

You broke a great ASUS VLB mobo to make a passive board? Your heart must be made of stone! Was there no junk available, like some PCchips with fake cache soldered on or Lucky Star with smelly VRMs? Please tell me the board was not functional... Lol, I'm more than glad to read this and my heart is …

I see those regularly, and wondered what would happen if for example, I put an ISA 486 computerboard into a 386 motherboard, removing the ram and cpu and bios from the 386 motherboard ? Unfortunately, this may not work if the subject is an industrial SBC. An industrial SBC and a normal motherboard …

Have a look at the numeric part of the partnumber. If it ends with a "0" then you have FPM memory, if it ends with something like 3, 4, 5, 7 or 9 then you have most likely EDO memory. Me too -- I applied this trick every time in a recycle store and identified EDO or FPM SIMMs without single mistake …

Apparently, this in-memory cache scheme was an early attempt of integrated L2 cache, which was eventually defeated by the in-CPU L2 cache scheme since PPro.
