Incorrect DMA
First off so as not to confuse anyone, ignore my signature because this post is for a different system.
Slackware 9
Abit BE6 (Highpoint HPT 366 ide & PIIX4 controllers)
P3 500Mhz
I'm using the Highpoint controller, not the PIIX4 controller and I cannot get the OS to correctly set DMA for my primary hd. The Highpoint BIOS detects it correctly (UDMA 4) but, when the system is done booting hdparm shows it as *UDMA 2. When I change the setting with hdparm it shows up as UDMA 4 but, 'hdparm -Tt' still produces the same results. Also, passing 'ide2=ata66' to the kernel doesn't work either. Here is some info:
