Re: [Xen-devel] IDE CD-ROM drive problem
The only platform I've been able to test this on so far is a VMWare setup (I
don't imagine native hardware being different, as I've had the same results
from both thus far), but here are the results. If I boot now with no disk in
the drive, it reports "No medium found" in the drive, even when I put a disk in
the drive to mount. If I boot with a disk in the drive, then it behaves the
same as it did when I removed the block of code in xenolinux_block_open().
I will try and get the boot output to dump to a serial file and post it
tomorrow.
I concur, though, looks like bringing in all the CD-ROM code would be icky...
