I get 13 MB/s on my Seagate Medalist Pro 9140 this way. wdc0: unit 0 (wd0): <ST39140A>, DMA, 32-bit, multi-block-16 wd0: 8693MB (17803440 sectors), 17662 cyls, 16 heads, 63 S/T, 512 B/S st-lcremean:~ $ dd if=/dev/rwd0 of=/dev/null bs=1024k count=30 30+0 records in 30+0 records out 31457280 bytes transferred in 2.295490 secs (13703950 bytes/sec) However, if it only does 2.4MB/s writing on the Acer, it may be that UDMA isn't getting enabled correctly. Which rev of ide_pci.c do you have? PS: I can put up the M1543 programmer's manual on my machine if you want to fix it; I don't have my Acer board here anymore, so can't do this myself. -- +--------------------------------------------------------------------+ | Lee Cremeans -- Manassas, VA, USA (WakkyMouse on DALnet and WTnet)| | lcremean@tidalwave.net| http://st-lcremean.tidalwave.net/~lee | To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the messagehelp
