Please help - problems with Ultra DMA
I'm trying to enable Ultra DMA on a woody system running a 2.4.17 kernel. I've enabled the applicable kernel options. CPU is Athlon 1700XP Motherboard is an InnoBD BD7300D, with: VIA VT8366A (KT266A) North bridge VIA VT8233A South Bridge Disk drive: Maxtor 5T06086 60GB 7200 RPM But when I type 'hdparm -d1 /dev/hda', I get setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted /dev/hda: using_dma= 0 (off) and yes, I'm running 'hdparm' as root. I'm writing to this list as a last resort, because the HOWTOs and manpages say nothing about this, and Google brings up a whole bunch of unanswered questions on mailing list archives (which I hope this won't end up as). Can someone please shed some light? Thanks so much in advance David -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]

In the bootup msgs, I'm getting 'VP_IDE: Unknown VIA Southbridge", for the VIA VT8233A chip. > On my > PIIX4 the kernel detects it and enables the maximum ultradma completely > automatically.

Google gives lots of mentions, but not the actual patch itself.

Try /pub/linux/kernel/people/hedrick Thanks to Vojtech Pavlik's suggestion, I've upgraded to 2.4.19-pre5 and now enjoy 35MB/s instead of 7MB/s on /dev/hda! - full UDMA :) And, 'hdparm -d1 /dev/hda' now works!
