biosboot(8) has an MBR boot signature. If the BIOS doesn't check for a valid MBR partition table--some do, some don't--then it should be able to directly run biosboot(8) from sector 0. installboot(8) tries to prevent such a configuration, but it could be tweaked, or you could try to tweak the disklabel and set the type to floppy, because floppies don't have MBR partitions. -- Christian "naddy" Weisgerber na...@mips.inka.de
