DOS ain't dead

QEMU and DOS (Ultra)-DMA drivers (Emulation)

posted by Japheth , Germany (South), 11.08.2022, 16:05

Hello,

Qemu allegedly supports just 2 "standard PCs": an i440FX (1996) and a Q35 (2009).

The Q35 is SATA (AHCI) only, so not very interesting here.

The i440FX has - according to docs - no support for UDMA. I checked WinXP running in Qemu: the HD is indeed accessed with mode "Multi-word" DMA 2.

So my question is: are there any DOS DMA drivers (UIDE, UDMA, XIDE, XHDD, ... ) that work with Qemu?
