>Description:
System had been running FreeBSD 4.11 perfectly. I attempted to boot a FreeBSD 5.4 RELEASE cdrom on it to install
5.4 and could not do so. After installing from floppies over the network I found that the computer was not detecting
the CDROM drive. I removed the drive and replaced it with a Sony drive that had been working in another FreeBSD 5.4
system fine, and had been detected as a UDMA33 drive in that system. That drive was detected in this system as such:
acd0: CDROM <CDU5211/YYS7> at ata1-master PIO4
I then took the drive that had not been detected in this system and installed it in the other system where I had
got the Sony cdrom drive from, and it was detected in that machine as such:
acd0: CDROM <Pioneer CD-ROM ATAPI Model DR-944 0107/E1.07> at ata1-master PIO4
Note that the specifications for both the Pioneer and the Sony drive claim UDMA33 yet the Sony drive was only
detected as PIO4 when connected to the Intel ICH ata controller. And in the other system which uses a
VIA 8233 UDMA100 controller, the Pioneer was also only detected as PIO4, even though the Sony was detected
as UDMA by the VIA chipset.
I don't know how relevant this is, but neither system had the 80 conductor ribbon cables attached to the CDROM
drives.
