If I would have known what I as getting, I wouldn't have bought the computer. The BIOS offers nearly nothing in the way of options. I do know it uses a VIA chipset and the AMD 751 chipset. I don't really have more specifics other than what you see in the dmesg. I will get you a verbose dmesg tonight. I will also see what BIOS settings are available. I do believe all of them are set to auto for the IDE interfaces.=20 I do believe the drive is UDMA66 capable - but I never looked into it. Perhaps I should get a different cable. Ironically, Linux drops that drive to PIO. > Because ATAPI DMA is disabled as default (the old driver didn't even have > DMA support for ATAPI devices), see lint how to enable it. >=20 > -S=F8ren >=20 Cool.
