Hello Everyone,
Despite the BIOS information about the nonexistent floppy, the zfsboot.c code
will prevent to boot from the first HDD if a floppy is given as a first available device.
The drive 0x0 (floppy) will be probed before the code below and an error occurs:
[…]
gptzfsboot: error 1 lba 32
gptzfsboot: error 1 lba 1
[…]
The continue statement will skip the rest of the iteration because
if ((i | DRV_HARD) == *(uint8_t *)PTOV(ARGS))
is true if the drive equals 0x80. As a result we do not call probe_drive()
for this drive.
Eliminating
if ((i | DRV_HARD) == *(uint8_t *)PTOV(ARGS))
continue;
would help.
Any comments will be appreciated.
Best Regards,
Christoph

* vdevs for the boot pool.

for (i = 0; i < *(unsigned char *)PTOV(BIOS_NUMDRIVES); i++) {
if ((i | DRV_HARD) == *(uint8_t *)PTOV(ARGS))
continue;
if (!int13probe(i | DRV_HARD))
break;
[…]
probe_drive(dsk, NULL);
}
