A bug in pbr.S perhaps
First, the pbr code rarely goes to no_netbsd_ptn in pbr.S, right ?
it will get there when no expected partition is found, and if the ESI
register holding the LBA sector number pass by mbr is not zero, maybe
there is a netbsd partition, so pbr code will try to clear the ESI
register and the lba_sector and then boot the netbsd partition found
The code is below:
205 /* Specific sector not found: try again looking for first NetBSD ptn */
206 testl %esi, %esi
208 jz error
209 xorl %esi, %esi
210 movl %esi, lba_sector
211 jmp start
But, the start's address is PRIMARY_LOAD_ADDRESS but not 0x7c00, so
maybe it will crash when booting the last-checked partition.
Thanks for any comments.
