That reminds me on some investigations I did as I was hunting USB boot device problems. Some BIOSes do not check the partition (slice) ID but are looking for a file system magic. If a FAT filesystem is detected, the BIOS does some stupid things (like ignoring the active partition flag and booting the FAT slice no matter what you've flagged active). Just an example and off-topic to Andriy's keyboard problem. But when combining that with your findings, it may still be a thing to check for... ;) Volker
