can you take a dump of the boot sector at various stages
indicated below:
> <snip>
DUMP #1: ORIGINAL BOOT SECTOR
<run boot0cfg -s 2 -v ad0 >
DUMP #2: AFTER THE BOOT SECTOR UPDATE
<reboot without pressing an F-key>
<expect to be in s2 but actually end up in s1, as you found>
DUMP #3: AFTER A REBOOT WITH NO KEYPRESS
<reboot, this time selecting the slice with F2>
DUMP #4: AFTER THE SUCCESSFUL BOOT IN SLICE 2
At least from this we can tell how #4 differs from #2/#3
cheers
