Would these cards be a priority since they already have original DOS drivers? The situation of AudioPCI based cards is similar to other Creative PCI cards ( SB Live, Audigy). Namely they use almost the same DOS drivers that stopped working a long time ago on Intel chipsets and never worked on …

Yesterday I tried to run sbemu on a MB with a onboard ES1371 sound hw. It was accespted by sbemu, but no sound was rendered. I checked the source, added the missing IRQ routine and activated interrupts, but this didn't help. Running MPXPLAY on this MB revealed that it also had problems ( no sound …

Thanks for the reply. I have already tried two different floppy drives. Both had their original belts completely worn out and I have tried two different new belts in each drive, with no luck.

this is not meant to be critisism in anyway, but more my thinking. Compaq Bios is so terrible, that non system disk or disk error can mean anything.

You'd order boards from a PCB manufacturer like PCBway, JLCPCB or another like that. They're usually not cheap in the UK/US etc, but the Chinese PCB makers are quite cheap. Then you'd need to order the parts in SanguineBrah's post and solder it all together. It might be nice if an adapter like this …

This is a late reply but the Compaq LTE Elite only support 1gb CF cards or smaller. Anything larger than that will give you trouble/not boot. I used anoter laptop to install dos/windows setup files on the CF and then transferred it to run/install on the LTE Elite. It worked. This guy made some …

PATCHMEM + 2GB of RAM = Duke3D works! I have added an update, PATCHMEM now has a config where RAM is limited to 2048 MB of RAM. This allows DOS4GW games like Duke3D to work. The previous limit of 2458MB (or there about) caused errors, while simpler games like Keen 6 worked. So this increases …

On my own system 512MB indeed works for most but not all, 256MB is safer which is why i use 512MB inside 98 and 256MB inside DOS. Might even lower it further in the future on my own config since does really doesn't need that much. I'm tempted to include a set of batch scripts that will update the …
