SubjectRe: ide.2.4.1-p3.01112001.patch
From

Alan asked:

My board here is a FIC PA-2013A (if I recall correctly; the
motherboard only has "PA-2013" on it, no "A") rev 1.1.

It's worth noting that there is at least another full revision level
(2.x), and the BIOSes for these different revisions are *not*
compatible (as I found out to my chagrin ;-).

Also, the FIC PA-513 (maybe 512?) should be a very similar board, only
wired for an AT power supply where the PA-2013 is an ATX board.

I've never seen the DMA data corruption on this box, but I'd really
really like to get something better than 3MB/s off my UDMA/66-capable
drives. I'm pretty sure that (prior to the 2.2.18 squelching of all
VIA IDE UDMA) that hda and hdc would come up with DMA enabled, at the
very least. Is there a safe way to test various hdparm settings? I'm
even willing to buy a scratch disk if that would help...

Looking at the chips, I have:

1. VIA
VT82C598MVP
9828CE Taiwan
13G003900

2. VIA
VT82C586B
S7-SB
9826CD Taiwan
14B013511

It has an Award BIOS with a variety of WinBond support chips (looks
like at least 4 on-board cache chips, and one near the BIOS EEPROM).

Here's the relevant dmesg bits:

I've included "hdparm" and "lspci -vvxxx" output below, omitting
non-chipset related things (SCSI, Ethernet, and VGA). If it matters,
this board is running 100MHz FSB with a 450MHz K6-3 CPU and 384MB (3 x
128MB DIMMs) of PC-100 SDRAM.

If I can provide any more information, please don't hesitate to ask.

Thanks,
