Hi Eric,

No, both XDMA and UDMA2 only support int 13 devices. If you have
a NON-int 13 device on the same cable, you can even get transfer
troubles (when your CD driver and the UDMA2 DOS harddisk driver
both try to use UDMA on the same cable). Note that drivers like
VIDE-CDD often do support UDMA already. So if you have CD/DVD on
one cable and harddisk(s) on the other, use UDMA2 (or XDMA) and
VIDE-CDD and be happy.

Ah, that makes a lot of sense! Thanks for explaining it - I never understood CD/DVD in the context of DMA.

No, it is a smaller variant of it. Unless you are into embedded
systems or into squeezing out every byte of free RAM, you probably
better use the normal UDMA2 driver instead.

OK, thanks again.
