cdrw & PIO4
Hi, I have a CDRW drive which is detected by the BIOS as UDMA2, but when FreeBSD boots it gets set to PIO4. Im using FreeBSD 4.7. Its attached using a ATA133 compat cable, and its the only device on that controller. Does anyone have any tips on getting the CDRW drive set to UDMA mode? Please email me personally, since Im not subscribed to the list. Thanks. __ Do you Yahoo!? Win a $20,000 Career Makeover at Yahoo!
