As an added bonus, I was able to get Ultra DMA at least partially working -- reads work beautifully, pulling down 13+ MB/s from my Seagate Medalist Pro 9140, but writes were kinda recalcitrant, and I think that may have been because I overclocked the PCI bus on my board -- I need to test it at 33 MHz. I can't work on this seriously anymore because I've since returned the board to its rightful owner (who was letting me borrow it indefinitely), and now have a VIA-based Super7 board (Soyo SY-5EHM). I'll put the patches for the Acer chipset on my webpage. I NEED TESTERS FOR THE UDMA. They'll be available at http://st-lcremean.tidalwave.net/~lee/acer-udma.tar.gz -- +--------------------------------------------------------------------+ | 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 message
