You can also consider an SD card to IDE adapter. Their prices have come down and SD cards are more readily available than Compact Flash cards

I even got mine to boot by removing the HDD and booting from FDD. It wouldn't save the HDD parameters and without HDD Auto Detect no IDE HDD would ever work without a good battery. Even though the FDD defaulted to a 5.25 1.2 MB drive in BIOS I could use a 1.44MB 3.5 disc, it just wouldn't read past …

I have the same motherboard and, to get it to POST, I had to replace the Dallas RTC (fortunately, I was able to secure a "new old stock" Dallas RTC that still worked fine). This motherboard is very similar to the OPTI495 chipset-based range of "hybrid" motherboards that could also accept both 386 or …

As memory serves, the MT-32 soundbank/soundfont (shipped with the AWE range of cards) only contains a small number of additional samples for the MT-32 (that isn't part of the standard GM sample set) and, then also rearranges (maps) the rest of the standard GM samples to more or less match the MIDI …

There were minor differences between the AMD & Intel versions. Don't see why it shouldn't work if you jumper everything correctly. Intel was a 3.3V CPU. Try going into CMOS setup and load the default values, save and exit, go back again and tweak for best performance

In case anyone is interested, I spent some more time fiddling with it, ended up ordering a bulk pack of replacement belts on ebay since it was only a few bucks, replaced the belt and it's back to working condition! Cheap and easy. Really glad it worked out as it's the original CD-ROM from 1997 and …

You need to ensure that you connect the cable correctly. From the sound card it's MIDI OUT going to the MIDI IN on the MT-32. Depending on the cable you bought, the wording is flipped around (i.e., the part that says OUT on the cable goes to the IN MIDI port on the MT-32). Make sure the MPU-401 MIDI …

I'm talking about something like this: http://sullystationtechnologies.com/npninverter.html . I'm saying this because, if i remember correctly some old motherboards had the 'turbo led' signal inverted from the factory so they could work with a speed display. Ok, thanks. Let me do some further …

Hardware solution: check at the tb led connector, and depending of what type of driver conf the board uses for that led this could work (can't damage anything if you don't mess with anything else!), you should have 2 pins. One has the signal for the led and one should be ground or 5v. Depending on …

Just to add to vstrakh's post. The top pair are 1 MB simms each. Since there are 9 chips on each module, the one is for parity but, the access time for these chips are too slow in terms of the requirements for the Sound Blaster 32. The bottom simms should work but, there might just be an …

Could also be a speed issue, this is an old card and that is an Athlon motherboard. Recently got one of these working.

Agreed what others have said. In short, you are more likely to first run into a CPU bottleneck then a RAM limitation with the hardware you described.
