Hi Andre, Alan
afaik the opti621 can't do DMA, also aren't they all addon cards?

The Compaq Armada 1530 Notebook has a Opti FireStar chipset with an IDE
controller which is Ultra DMA capable (but stable only up to MW-DMA
mode 2). This one *should* be handled by the Linux opti621 driver (I
don't know if it is).
Ciao,
Dani

I'd be interested to see an lspci, I'd be mortified if the opti621
driver really drives that controller ;)

Actually, it's an 1575D.

No Linux on that machine, thus no lspci but something similar:
Vendor 1045h OPTi Inc
Device C701h 82C701 FireStar Plus CPU to PCI Bridge
Subsystem ID 0E1103F4h Compaq Armarda
Vendor 1045h OPTi Inc
Device C700h 82C700 FireStar PCI to ISA Bridge
Subsystem ID 0E1103F4h Compaq Armarda
Vendor 1045h OPTi Inc
Device D568h 82C825 FireBridge II PCI EIDE Controller
Subsystem ID 0E1103F4h Compaq Armada
This should be supported by the opti621 driver.
With these devices
disk :IBM-DKLA-23240 (primary master) running at MWord DMA2/PIO4
cdrom:UJDA120 (primary slave) running at PIO4
the chipset shuld be programmed like this:

If you like to run the disk at ultra DMA mode 0, then it looks like
this:
