I've got a Diamond Max Plus 20GB HD, it's 7200 RPM and ATA66. Right now,
performance is terrible. DMA is not being enabled at boot.
I read on Maxtor's support page that older MBs (I've got a BH6) with
Award BIOSes don't always report that the drive is capable of DMA mode
2, so I used Maxtor's util to cause the drive to report itself as a DMA
mode 2 drive, but this did not help. Here's my info:

Distro is release 7.0, Kernel 2.2.14-15mdk.
Any suggestions? The kernel warning really has me worried....
