Hi:
Please read the whole post before replying. Yes, I know that
DOS allows 4 PRIMARY Partitions and the history and purpose
of an EXTENDED Partition.
I am installing 4.7-REL on a PC with one PRIMARY and one
EXTENDED partition. The PRIMARY partition is FAT and I have
W98 there. The EXTENDED partition is empty as it was originally
set up to be a place for FreeBSD. Unfortuneately, I now
understand that FreeBSD needs to be in a PRIMARY partition.
(EXTENDED was recommended by the disk's customer
service rep was was familiar with Linux but not BSD)
Also, SYSINSTALL's FDISK program says that one should put
FreeBSD in a partition labeled as "unused". However, the
"Change Type" command lets me change the EXTENDED
partition to FreeBSD. I tried it and it seemed to work (I could
even make it "bootable") but I decided not to proceed because
I don't know what is going on behind the scenes: is it really
changing the partition to PRIMARY or just making a label
change (is that the same thing)? I don't want to wind up
with a disk that is unuseable. And if it is making the
change from EXTENDED to PRIMARY, is this something that
the BIOS will be OK with?
Alternatively, should I use the SYSINSTALL/FDISK "Delete"
option on the Partition and then create a new partition/slice
instead of "Change Type"?
If SYSINSTALL's FDISK program will not do what I need can you
direct me to a tool can I use to change the EXTENDED partition
to a PRIMARY partition?
Thanks,
John Daniels
FYI, SYSINSTALL's FDISK screen is:
Disk Name: ad0
Disk geometry: 4865 cyls/ 255 heads / 63 sectors = 78156225 (38162MB)
