Subject: [9fans] Plan 9 boot block question
Topicbox-Message-UUID: bd66750e-eac8-11e9-9e20-41e7f4b1d025



If I understand things correctly, the 512 first bytes of the Plan 9
partition contain some code that loads a secondary boot (9load).
But if I compare these bytes with /386/pbs or /386/pbslba via cmp,
there is a difference. Is it normal ? If I write /386/pbs or
/386/pbslba on this sector, will I still be able to boot ? If
I crunch this block, what is the clean way to restore it ?

(A mail bounce later: writing /386/pbs on this sector makes the
partition un-bootable. saving this block under another unix and
writing it back after the failure is not enough to restore things).
