Dear all,
I downloaded and attempted to install the 7.0-BETA2 ISO on a Parallels VM
yesterday, and fairly rapidly ran into problems. I configured the ISO to
appear as a CD-ROM drive in the VM, and booted: it happily got to sysinstall,
but when I began the install, sysinstall was unable to mount the install CD.
Booting to an existing 7-CURRENT VM, I found that it also was unable to mount
the CD, but that I could install from a 6.3-BETA1 ISO without a problem.
Testing from the command line, "mount -t cd9660" on 7.0 returns:
mount: /dev/ac0 : Input/output error
The same command on 6.3 successfully mounts the image. On the general theory
of things, I tested mounting the 6 ISO on 7 (failed) and the 7 ISO on 6
(succeeded). In both 6 and 7, the virtual CD-ROM drive appears to probe fine:
acd0: DVDROM <PRL CD-ROM [1]/FWR10003> at ata0-slave PIO4
In both cases, the drive continues to show up fine in atacontrol:
Slave: acd0 <PRL CD-ROM [1]/FWR10003> ATA/ATAPI revision 4
I tried reconfiguring Parallels to move the ISO to the second virtual ATA
controller and that didn't make a difference either. I was wondering if
anyone else had seen this? It sounds like it may be a change in the ATA
driver?
