If I had an audio cdrom in my cd player when I booted my system, I'd get a panic from geom because you can't read 8192 bytes from an audio cdrom. Remove XXX comment about IPL1 and replace it with some information from my soon to be published web page on the pc98 disk layout. The IPL1 test was the result of an observation of a disk with FreeBSD's boot0 program. It was testing part of an area what appears to be reserved for a boot loader name, which comes after a jump over this area. I don't yet know if it is required to be any specific jump instruction, or if the destination has to be location 11. [1] [1] FreeBSD Press No. 13, page 115, poorly translated by myself. The picture there shows offset 8 as the destination of the jump, but FreeBSD's boot0 program has three padding NULs after the IPL1 name and uses a 16-bit 'jmp' instruction. |
