[...] That's probably also why my Dad's M24 didn't turn on anymore when I tried it a while back. @dionb Is it okay if I reach out in a DM to inquire about more info on how to fix this? Thanks! Given I haven't fixed it either, I'd suggest you'd have more luck with a separate topic here so others can …

My M24 is dead (PSU RIFA went boom and I've not yet had time to replace), but IIRC the M24 used 25kHz output for its higher video modes. Could that be why they're not displaying correctly?

Me too, but when things don't work I try other options... Default for SB16 is DMA1 low, DMA5 high. Using DMA3 for 'high' DMA was more something for buggy boards that didn't support 16b DMA properly, or ALS100+/120 chipsets that only implemented double-low DMA for their SB16 compatibility. I don't …

On my board, there is no DMA support on the ISA bus. My guess is that the other reference is a mistake, unless he has some other board revision or a different bridge chip. It's important to clarify that Adlib sound will always work, regardless of DMA, and this can be misleading. DMA is only needed …

The only way to be completely sure you won't bottleneck on GPU is to bottleneck on CPU - the system will always bottleneck on one or the other. The only potential reason it might hurt to have a newer GPU is that it forces you to use newer drivers with more overhead - but GF4 isn't that different to …

Correct, no need to modify your Voodoo's although admit I like to have a bit extra just for peace of mind.

What motherboard do you have? 5.25" support was dropped in the last generation of boards with floppy (WinXP era); immediately before that the option was still there but I'd be surprised if anybody did Q&A on it...
