It was a compatability issue with the motherboard. What was happening was that the BIOS was recognizing the UDMA/66 capability of the harddrives, even though the chipset is only capable of UDMA/33. I belive when FreeBSD was requesting a DMA transfer the system was trying to use UDMA/66 and failing.[ A BIOS update that limits to UDMA/33 resolved this problem for me. -Chris On Tue, 14 Dec 1999, Strange Alex wrote: > Hello ChrisMic, > > > wd0: UDMA/66 capable 10.2GB Western Digital Harddrive > > wd1: UDMA/66 capable 20.2GB IBM Deskstar. > > > The flags on the controller is 0xa0ffa0ff. > > > When I boot the system with UDMA mode enabled in the BIOS I get the > > following 2 error messages. > > > wd0: reverting to PIO mode reading fsbn 0 (status 51 error > > 84) > > wd1: reverting to PIO mode reading fsbn 0 (status 51 error > > 84) > > Did you solve this problem ??? > > > Regards, Aleksey Rusanov > Unicon+ Ltd, Novosibirsk > Unix network administrator > Phones: +7 3832 23-94-06 > +7 3832 10-00-50 > Fax: +7 3832 23-94-06 > ICQ UIN: 8397628 > URL: http://www.unicon.ru/ > http://www.H-ck.ru/ > > To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
