Being an owner of a standard Orchid Soundwave 32, I'm following this thread with interest. My card has the standard ROM images, but I have acquired two 512KB ROM chips in order for me to try out the Invision ROM images. Just haven't got around into testing it out.

Hope I understand you correctly. Create a [Common] section in your Config.sys file and place those two device drivers under that [Common] section. Then, regardless which menu item you choose, it will always load whatever is listed under that [Common] section. Also refer here for more examples: …

Great find - if you can obtain one of those Local Bus graphics cards (not EISA as "Disruptor" has pointed out), then you will have equivalent performance to that of a VESA Local Bus graphics card. However, considering that you only have a 486DLC CPU on there, you will most likely not benefit that …

You basically require two drivers. One that comes with DOS (there are alternatives out there) called MSCDEX.EXE and the device driver for the CD-ROM drive itself. I prefer the one called VIDE-CDD.SYS, but the one that comes with the Windows 98 startup disk is called OAKCDROM.SYS. You can take the …

The Asus PVI-486SP3 does not officially support a 50 MHz FSB (at least, not according to the revision 1.3 manual that I have and they even inserted an addendum in the manual specifically stating this). I do agree that it is a very nice motherboard, but I don't think it will be suitable for this …

You could perhaps just try using wooden dowel pins? Measure the diameter of the holes and buy the appropriate sized dowel as a spacer.

Another alternative would then be a diagnostic card or EEPROM - with the latter, try the SuperSoft/Landmark Diagnostic ROM available on minuszerodegrees.net. You will need an MDA or CGA card with the appropriate monitor to see what's being displayed (and of course a blank E(E) PROM and burner). …

Doom just loves the 486 architecture. The SX-16 is very close to the DX-40 in Doom, but quite behind in the rest of the benchmarks. Interesting results though, as I was competing with my friend's SX-25 when I was young (I had a DX-40). Mine had 128kb of external cache, and his didn't have any, so …

Just curious - most protected mode games only came out after 1993, when General MIDI was already the standard for games and none required an intelligent mode MPU-401 MIDI interface. Why do you then need SoftMPU? Just route the MIDI straight from any sound card with an onboard UART mode MIDI …

How are you flashing the ROMs? With an EEPROM programmer? There is a DOS utility included with the XT-IDE BIOS. Try using that when flashing the BIOS directly on the NIC.

When you overclocked the FSB, did you also change the clock divider in the CMOS setup? At 33 MHz, it should have a divider of 4, but at 40 MHz it should be 5. By keeping the divider at 4 and with a FSB of 40 MHz, you're running your ISA bus at 10 MHz, which could be the cause of your problems.
