The Audigy is a "modern" card so the joystick port is unlikely to work in DOS. Even the earlier SBLive needed special emulation drivers to work in DOS, which I think they stopped supplying with the Audigy. So as far as DOS is concerned, you will only have one card - the Audigy will be invisible. In …

That's much more helpful! Thanks for the clear photo. Because those sockets have no locking mechanism and the CPU is held in by friction, you can often need quite a bit of force to lever them out, even if they are called "low insertion force" sockets. The suggestion of tayyare's to use a slot cover …

Yes unless you can move it to a different I/O port to avoid a conflict. Or use one for joysticks and the other for MIDI, which use different ports. I'm not sure whether the MIDI portion still works if you disable the joystick, but it might. You might also have issues detecting the OPL chips if they …

Have you tried running Memtest86? It's probably not a bad stick of RAM but the problem might show up as such. I believe Memtest86 will also test the L1 and L2 caches on the CPU which could also be where the problem arises. Might just be unfortunate that the CPU got a minor static electricity shock …

It's possible for a processor to be pushed into a socket, this could look like there's a black plastic holder between the CPU and the motherboard. It's also possible for the CPU to be soldered into the motherboard, in this case there could be a spacer which will look like there's a black plastic …

Actually now that you mention it, I think it did lock the disk in. The drive was in unknown condition so I think (rather embarrassingly) I assumed the eject mechanism must be broken so I was using the emergency eject hole to get the disk out. If you say the disk gets locked in until reboot then the …

Etherboot supports the 3c509 and can be burned onto a ROM, so you should be able to add PXE support to a 3c509 ISA card with that. Not sure what the minimum CPU requirements are for Etherboot though (it only says "x86" but not whether that means i386, i686, or what.) Etherboot has changed to gPXE …

If you have the ATA version you won't need drivers, if you have the ATAPI version you need to install the Iomega ZIP drivers. ATAPI is just a communication protocol. CD drives use it, but it's not *for* CD drives. DOS doesn't support ATAPI devices natively, so for CD drives you need a CD ATAPI …

You could also use cheap USB to parallel adapters if you only have a parallel port available on the older hardware. The problem is that the parallel port was only designed as a one way interface, and over the years there are at least four different ways that it has been converted into a …

Like I said above, you do it the way Samba does. First file is FILE.TXT, second is FILE~1.TXT, third is FILE~2.TXT, etc. That problem has already been solved. Heck even DOSBox does it this way, but most people don't even notice because you never have files named like this anyway unless something has …

Sometimes drives made for big-endian architectures seem to have the letters swapped in the names (e.g. the BIOS lists the drive as "aMstsuihat" instead of "Matsushita", every two letters swapped) but from memory those drives still work.

I've also found that storing the cards in opposite directions (so every second card has the slot bracket facing the other way) allows you to fit twice as many cards into the same space. But of course my priority is fitting all the cards into the available space, and not about showing them off! I …

Yes that's correct, to the best of my knowledge. Yes, Windows ships with something named pscript.dll or similar. That renders PostScript commands from some other format, probably GDI.

Word talks to the Windows GDI, using primitives like 'write text' and 'draw line'. IIRC this step can be saved to a .WMF image file. If the target is a printer (as opposed to a window) then the GDI passes the commands along to the print subsystem and the printer driver. The printer driver then …
