Sounds like either your HD is going bad, or you have a bad burn of the iso.
Check the md5sum and try burning at slower speed.
Do you actually have SCSI?
I'm extremely sorry in advance if this is a common error or if I need to give more information. Google seems to turn up mostly posts about hd mounting.
After I get passed the boot prompt without any options (I'm not sure which option to select besides language) I get the error
scsi0: Error on channel 0, id 0, lun0, CDB 0x03
00 00 00 40 00 current sd0b: 00 sns=f0 3
ASC=11 ASCQ=6
Then there are Raw sense data erros and I/O error 0bi00, sector 569***
These continually loop.
Respectfully,
Exit
