There was ZIP-Disk in the drive, but not a bootable one. It is formatted as
partition disk with an extended partition and one logical drive.

Usetup doesn't use the information from bios.

The rdisk entry is used if the disk with the system partion is supported by
the bios. If there is no bios support, then is used the scsi entry and it
must exist the scsidriver on the root of the boot partition.

"15" is the partition type. It is an extended partition with lba support.
