Oh my God~~
My primary IDE master device was set in PIO mode.
It is a 120G Segate Harddisk, should be new enough to run in DMA mode.
I have tried but can't set it into DMA mode.
Please help.
Does it allow you to set it to DMA mode (but not select a specific mode)
and then on a reboot do the detection to pick which DMA mode?
Do you have any other devices on the same ribbon/round cable going to
the IDE hard drive (the one you cannot change to DMA mode)? If so, try
disconnecting that drive in the meantime to test if DMA mode can be
selected for the hard drive, and make sure the hard drive is at the end
of the ribbon cable.
If the hard drive is the only device on the ribbon cable, is it
configured as Single Drive or as Master Drive (for some drives they
differentiate between these two setups where Single Drive means there is
no other drive on the cable and Master Drive means it is set as master
and there is a second drive on the cable)? Do you have it configured
for Cable Select?
Are you using a 40-pin/80-wire ribbon cable, or is it the old
40-pin/40-wire ribbon cable? You should still be able to select DMA
mode 3 (UltraDMA-33) using the old 40-pin/40-wire ribbon cable.
What brand and model motherboard do you have? Does it use a non-Intel
chipset? If so, have you download and installed the latest chipset
driver package from the mobo maker's web site?
