TVGA8900 with 26 DIP switches, plus some jumpers... Why the hell such a simple card needs so many settings?

Certain groups collected all the copper electrical wire (sometimes panels) and burned the PVC off them to sell as scrap. It went as far as stealing material from construction sites and cutting LIVE WIRE from train lines! I know about a case when some guys stole optical fiber cables, and then tried …

"The Best Soundcard for the Internet" -- This is marketing at it's best. Why on earth would the GUS be good for the Internet? :) Safe bet it's supposed to mean the card supports full duplex, which is required for Internet telephony. In the 90s, full duplex wasn't obvious, non-standard configuration …

https://sites.google.com/site/misterzeropage/ There's an XT with 33 MB of RAM, so it's appropriate for an AT to have 48 MB!

Yep, and like I said, it might be a good idea to build a serial / parallel port or an AdLib clone or something in just so it will be multifunctional. But who needs such a multifunctional card? I/O cards are plentiful, and so are AdLib-compatible sound cards. Yes, there may be some PCs with few ISA …

So yes, the idea of a brand new 48 MB card seems more viable: - support for both 8- and 16-bit bus - various conventional memory options: 64K..640K for early 5150 boards, 256K..640K for late 5150 and early 5160, 512K..640K for AT, possibly some others - various upper memory options, maybe even 640K …

It seems not very difficult to find 2MB ISA memory cards for AT computers. You should build something more unique. For example, 8 to 16MB cards are pretty rare, and so are EMS 4.0 cards that can handle the full 32MB. Maybe a 48MB card should be ideal. 16 for the extended memory, and another 32 for …

Why should this be impossible? The BIOS can detect on which card it is running. It says "1542B/1542C/1542CF" in the BIOS' title screen, so... Adaptec mostly made BIOSes for larger groups of cards, not individual ones. But not really important, since I have no equipment to dump the ROM anyway. Then …

Bought this early 90s Adaptec AHA-1542B for my 386 build It probably has drive size limit of 1 GB. But there was BIOS/firmware update for up to 8 GB - most likely distributed in the form of ROM chips, nowadays nowhere to be found. If your card happens to support more than 1 GB, some may be …

When do you encounter that error? While trying to boot off that disk? There are some special requirements about location of IO.SYS and MSDOS.SYS files, so you can't simply extract them out of archive, you need to install them eg. with "SYS C:" command.

You need to run that SETUP.EXE under Windows 3.1 to properly install the software. It should install SNDINIT.EXE, which needs to be added to AUTOEXEC.BAT to initialize the card on boot.
