Difference in slice numbering FreeBSD 4.x vs. 6.x?

[Torfinn Ingolfsen]

It has been a long time, but today was a rainy day without plans, so
now I'm following up on an old thread.

I didn't have a live CD or fixit floppy at hand, so I just used the
"fdisk" menu in systinstall (on the 6.1-RELEASE / i386 cd).
It says that there are two slices:
ad0s3
ad0s4

Nope, it acts the same there - the boot manager says "F3" and "F4" aout
slices to boot from.
Unfortunately, the only slice it will boot is F3, which now is FreeBSD
4.11. Alas, the machine used for testing is a amd64 one, and it will
not boot 4.11 completely - it panics with a fatal trap 9 after a ad0
READ timeout and ata0: resetting devices ..

I'll guess that it is something I have done, even if I can't figure out
what.

For the record, I just wiped all slices on the hard drive, installed
FreeBSD 6.1-RELEASE (i386) on it, put it back into the
laptop and it boots with no problem. The PC card controller in the
laptop is still not detected, but that's another story.
