SubjectUDMA Problem on VIA chipset - K7M motherboard
In article <PstOfc.38b2e9f1.8b4567@DILITHIUM.MIT.EDU> you write:
> I do have the correct 80-conductor cable, counted the wires to make sure,
> and the drives definitely do support up to UDMA mode 4.

> and I'd love to get it to work. Thanks!

Support for the AMD7409 IDE chipset got added sometime in v2.3 - I'm
currently using 2.3.42 with CONFIG_BLK_DEV_AMD7409=y,
CONFIG_BLK_DEV_IDEDMA=y, and CONFIG_IDEDMA_AUTO=y, and getting dma
mode 2 without the massive corruption you (and I :-( ) saw in v2.2.
No hdparm'ing necessary.

FWIW.
