Hello!
looks like CD read errors..
This is not CD read errors."bios 0: drive 0x80: 80.026,361,856 bytes, type 3" - drive 0x80 is the hard drive, isn't it?
"biosdiskcall: int 13 op 0x42 drive 0x80 failed, ah error 0x80""sectread: bios failed to read 512 @ sector 0 of 0x80" - an error with reading of the first sector of the drive 0x80
