DMA support is very buggy, to say at least, for the Promise ata66 (PDC 20262)
and Abit HotRod (Highpoint hpt366). This is especially true for ATA-pi devices.
Your best bet would be, to put your regular CD-ROM player, ZIP-drive and other
devices that won't really need DMA support on your ata-66 compatible controller
and put your other devices (HD's, CDR's, DVD-players) on your main (Intel)
controller. (Don't forget that some ATA/66 compatible HD's (Like Maxtor)
required to be set to ATA/33 in the firmware, in order to function properly...)
Mandrake 7.0 didn't had DMA support for the hpt366, afaik, so that's why you
didn't ran into trouble..
