9null - report #9

[Iruata Souza]

Hello,

From the last report I solved the problems I was having and changed
util/mkdisk to mimic a Plan 9 installation disk creation/partitioning
to create a disk with 9null (pbs32 + 9pcload) installed.
A new program, util/9nconv, can be used to convert from a 9load setup
to 9null. It will overwrite the 9fat partition with the pbs and
9pcload, leaving the rest of the disk untouched.
The pbs, for instance, was changed to go even earlier to protected mode.

Next week I'll write the kernel loader application to reside in /boot.

Best,
iru

forgot to mention mkboot now builds the whole project and creates a
test disk at util/dsk0.
