there's something else...
should i use the via 4in1 drivers to enable dma?
but how?
from via.com.tw:
Step 1: To setup the driver, double click the "SETUP.EXE" icon or run
"SETUP.EXE" under VIA 4 In 1 Driver directory.
Step 2: Bypass the "Welcome" dialog by clicking "Next"
Step 3: In "Select Component" dialog, choose driver(s) you wish to
install by clicking the check box of each driver. Selected
driver(s) will display tick(s).
After selecting proper driver(s), click next
Step 4: Driver options select
"VIA ATAPI Vendor Support Driver dialog": <--------------*

"VIA_GART AGP Driver":
Install VIA AGP VxD in turbo mode, Install VIA AGP VxD in
Normal Mode, Uninstall
"Viamach.INF ":
