ATA100 PCI cards have been supported sinve the 22 kernel and the 2.4 kernel (including that in 7.1) supports the onboard controllers.
Hi Charles, Your response prompts me to ask whether you know what sort of transfer rate I should see. I have a correctly cabled IBM Deskstar ATA 100 (DTLA 307030) running under 7.0 and my home-compiled 2.4 kernel on an 815e mobo (Asus cusl2). So far as I can tell I have set everything correctly in the kernel, including dma. Hdparm reports UDMA mode 5 in use. When I run hdparm -tT, however, I see : /dev/hda: Timing buffer-cache reads: 128 MB in 1.03 seconds =124.27 MB/sec Timing buffered disk reads: 64 MB in 4.13 seconds = 15.50 MB/sec I know that hdparm is a crude tool for benchmarking a hard drive, and that one never gets the "full" transfer rate in the real world, but 15.50 MB/sec, seems very slow. I would be grateful for any observations / advice. Regards, Geoff _________________________________________________________ Do You Yahoo!? Get your free @yahoo.com address at http://mail.yahoo.com
