I understand the "hitorical" use of the table,
but it is working in the 1.6.0
total sectors: 26704944
headswitch: 0 # microseconds
track-to-track seek: 0 # microseconds
# size offset fstype [fsize bsize cpg/sgs]
a: 10239453 16465491 4.2BSD 1024 8192 93 # (Cyl. 16334*-
b: 524288 16065 swap # (Cyl. 15*- 536*)
c: 15925138 540353 4.2BSD 4096 32768 1184 # (Cyl. 536*-
d: 26704944 0 unused 0 0 # (Cyl. 0 -
f: 16002 63 Linux Ext2 0 0 # (Cyl. 0*- 15*)
This is what I did
and after booting into 2.0
wd0c shows and mounts as wd0a (wd0a is still the same as before)
So to me it looks like disklabel/the OS does not READ the partition table,
I believe this would be just a table on the disk....
So does this mean 2.0 ignores the table ?
Shall I hand patch the table for 2.0 ?
scares me a bit,
I definetly do a backup firt :-)
