The mp3 player I'm using does require an FPU and will not operate in Windows 3.1 without one. It was noted above, if you try to run it without an FPU, you get "WinPlay3 requires a 486 Processor with a build in FPU". It is only the 32-bit version of the same player from within NT 3.51 which tries to …

Yeah, the labels for that area read left to right but the actual component is supposed to be installed 90 degrees from that writing. If I had been looking closely, I would have seen that they didn't line up with the lines on the board properly but there was well over 200 of those small 0402 …

AlaricD, unfortunately, I only see Linux files for Madplay. Audacity has Win98 minimum system requirements and looks relatively modern. From your comment of 'players from that era', I was expecting something circa 1994. I normally use Windows 3.11 and NT 3.51 on 486DLC era hardware. I didn't …

I didn't mention an era for the mp3 player I'm using. If I remove the FPU, the player won't play the mp3 file very well. It tries, but there will be 10 second gaps of silence. As a follow-up to my previous comment, AlaricD, could you let me know which mp3 players do not use the FPU? I would like to …

One of the tests I like to do is play a (downsampled) mp3 file in Windows, while trying to access the floppy drive. Presumably, this tests floppy DMA, sound DMA, and FPU interaction in one shot. .MP3s often use fixed-point arithmetic for compression, and any players (and compressors) from the from …

Do you have something like a Kill-A-Watt meter? If the power usage is suspiciously low, it could be the flyback transformer itself. That it plays sound is otherwise a good sign, though. I'd take a peek inside to see if there are any obviously-blown caps and stuff like that (of course, it shouldn't …

How do you know if it is [Plug and Play]? It's a ct4380 awe64. The CT4380 is PnP.

If there are two PnP …

A single install with hardware profiles may yet be cleaner, as separate versions may become unwieldy with satisfying .DLL / .VXD dependencies and making sure the Registries are aligned with respect to certain software installations.

I guess I had it in my mind that a dual-boot Win98/XP might be set up with an ISA audio card for Win98 gaming, and PCI audio for XP-- but now I realize OP hasn't detailed what motherboard and cards he's working with. I can add some context. I'm currently working on a multi-OS build (DOS/Win95/Win98 …

You MIGHT run into a situation where XP wants to assign a PnP device to a different IRQ from Win98, so be careful to force those configurations to match to prevent device conflicts from randomly occuring (with the *enabled* hardware, of course). In the BIOS you can manually assign IRQs to PCI slots …

With luck, the pinout on the drive itself will be marked with R, G, L, and possibly O. RGGL would be "Right, Ground, Ground, Left"; ORGL would be "Open (or 'not connected), Right, Ground, Left" and so on. I think the Panasonic input is RGRG (Right, Ground, Left, Ground), so you could just cut the …

Both Win98 and XP support hardware profiles, so you could create separate hardware profiles with the devices you want active. Disabling the device in Device Manager is better than not installing drivers, because that would speed access to that hardware when needed (if it's just in as "Unknown Device …
