Yeah!  It works.

/dev/hda:
 multcount    = 16 (on)
 IO_support   =  3 (32-bit w/sync)
 unmaskirq    =  1 (on)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 readonly     =  0 (off)
 readahead    =  8 (on)
 geometry     = 4864/255/63, sectors = 78140160, start = 0

Put a BS-Ware on order for me this week.

BTW,  "ide: Assuming 66MHz system bus speed for PIO modes" in dmesg.

Is that the max speed,  don't some do 100MHz now?  Can I add idebuss=100
in grub.conf and get even more vrooooom?  This hard drive needs ALL the
help it can get;  one thing I miss is that snappy SCSI feel.
