2) I could not get UDMA working with neither 2.4.10 neither 2.4.16 SuSE kernels. Below is startup log. I have Maxtor 40 GB 7200 rpm/UDMA133 HD + NEC DVD and Chaintech m/b with VIA KT266A chipset (BIOS setup, cables are OK). Anyone knows how to make them work together in UDMA 100 mode? hdparm reports that UDMA is running for hda (but not DVD), but I am not sure, because hdparm seem to check its settings rather real hardware state. Also, how to tell hdparm to run in UDMA100, not UDMA33 mode?
You need to research a little about hdparm. The tags to find out more about are "-I" and "-X". "-I" checks the hard drive itself, instead of the kernel. "-X" allows you to specify the DMA mode. For example, "-d1 -X66" on my machine turns on UDMA2. You might also want to get the latest hdparm (version 4.6), because of its nicer output and (of course) bug fixes.
