Hello,
It is curious for me that if 9fat is formatted by disk/format of 9front,
then 9atom fails in boot with the error message
MBR...PBS2...Bad format or I/O errors
(or PBS1)
In making 9fat, I applied 9atom’s pbslba, 9load, etc except disk/format:
disk/format -b pbslba -d -r 2 /dev/sdC0/9fat 9load 9pc*f plan9.ini
I guess PBS2 claims that format of the allocation table is wrong
because if the 9fat is formatted by disk/format of 9atom
then 9atom can boot up.
term% xd -c /dev/sdC0/9fat # formatted using 9front
