Hello John,
First with printf() before
dsk = malloc(sizeof(struct dsk));
Attempting Boot From CD-ROM
Attempting Boot From Hard Drive (C:)
464: high_heap_size=0x300000; dsk=0x0; &bootinfo=0x8714 <--- the malloc() is next.
474: high_heap_size=0x300000; dsk=0xdf325000; &bootinfo=0x8714
probe_drive(): drive 0x80: type 0: unit 0: slice 1: part 0:
probe_drive(): drive 0x81: type 0: unit 1: slice 0: part 0:
BTX loader 1.00 BTX version is 1.02
Consoles: internal video/keyboard
BIOS drive A: is disk0
BIOS drive C: is disk1
BIOS drive D: is disk2
and now without printf() at line 464
Attempting Boot From CD-ROM
Attempting Boot From Hard Drive (C:)
474: high_heap_size=0x300000; dsk=0xdf325000; &bootinfo=0x86b4
probe_drive(): drive 0x0: type 0: unit 0: slice 0: part 0:
gptzfsboot: error 1 lba 32
gptzfsboot: error 1 lba 1
probe_drive(): drive 0x81: type 0: unit 1: slice 0: part 0:
gptzfsboot: No ZFS pools located, can't boot
