Anyway, have used UBCD since discovering 3.2. Great idea!
3.2 boots great. 3.3 wouldn't boot on my machine. Seemed at the time lots of others
had the same problem so thought it would be fixed. 3.4, however, boots in exactly
the same way that 3.3 won't.
Machine is pIII/800, AOpen AX6B+, 256Mb. 3xIDE HD. IDE Liteon DVD.
SCSI HD+Yamaha CD writer attached to on-board SCSI (AIC-7880).
UBCD 3.2 boots and runs from either drive. Ditto any version of Knoppix...
I suspect SCSI is the problem.
Another machine, p-pro with Adaptec 2930 SCSI card also fails to boot 3.3 or 3.4
from IDE or SCSI in the same way.
When trying to boot from IDE drive: error=80800279
When trying to boot from SCSI drive: error=808003F9
I can't not use SCSI so 3.3 and 3.4 are useless to me

Hope this is useful to finally fix this bug for 3.5!
