>Description:
FreeBSD 4.0 has a "WRITE command timeout - resetting" problem on VIA 
chipset.  This VIA chipset is Apollo Pro133, the older one with NO AGP4x
support.  More specifically VT82C693A North bridge and VT82C596B South 
bridge.  Kernel does detect upto UDMA 2 or ATA-33 and the chipset.  
Disabling the UDMA makes it ok but I don't want to disable the UDMA.

The motherboard is an ASUS P3V133.  I have the same setup at home using
an ASUS P3B-F with an Intel BX chipset, works fine at UDMA 2.
>How-To-Repeat:
Turn on UDMA from the BIOS any 0,1,2,3,4 will repeat this problem.
I have done this 3 times.  Installation will only work with UDMA disabled.
