Hi,
if I didn't make the same mistake again and again, I think it's a bug.
I installed (3 times) FreeBSD 2.0.5 from nutcreeker's CD on my
486DX2/66-ISA machine with 2 AT-Bus Conner 544CP (1st and 2nd)
and a hp 2GB SCSI drive (3rd), a NEC CDR511 and a Wangtek 5525ES tape
at an Adaptec 1524B, finally an ET4000 from TsengLabs (TurboMegaEVA).
(Forgotten anything ? :-)
Bug description:
* The partition table of my first HD (1st Conner) is garbled after
installation of FreeBSD-2.0.5 --- the entry for my ISC-Unix partition
is zeroed.
* The Extended DOS partition on the 2nd HD is not recognised.
My partition table for 1st HD looks (using Norton Util.) like:
Start End
System Boot Sid Cyl Sec Sid Cyl Sec Offset Size
DOS-16 (4) No 1 0 1 15 64 63 63 65457
FreeBSD (165) No 0 65 1 15 227 63 65520 164304
ISC-2.2 (99) Yes 0 390 1 15 1023 63 393120 669312
Solaris (130) No 0 228 1 15 389 63 229824 163296
The Conner 544CP is seen with 16 heads, 63 secs/tr and 1054(1053) cyls.
(Solaris was never installed since it refuses to create a partition
on the 2GB-SCSI disk as it sees a different geometry than all other
systems)
The Partition menu says for wd0:
Offset Size End Name PType Desc Subt Flags
0 63 62 - 6 unused 0
63 65457 65519 wd0s1 2 fat 4
65520 164304 229823 wd0s2 3 freebsd 165 C
229824 163296 393119 wd0s4 1 unknown 130
393120 668304 1061423 - 6 unused 0 >
After installation I had to manually edit the partition sector to boot
ISC-Unix again (which I still run because of its VP/ix when I'm
developing DOS-programs -- will there ever be a DOS-emulator under BSD
running at full speed and providing a virtual environment (esp. HDs) ?)
In the label menu, only the primary DOS partition of the 2nd HD is
recognised, the ExtDOS is ignored.
My partition table for 2nd HD looks (using Norton Util.) like:
Start End
System Boot Sid Cyl Sec Sid Cyl Sec Offset Size
DOS-16 (4) No 1 0 1 15 64 63 63 65457
ExtDOS (5) No 0 65 1 15 1023 63 65520 966672
The label menu only shows wd1s1 (to mount under /d).
The rest of the installation went fine, except for some warning on vt1
that for sd0 the calculated sectors per unit (4000) is different from
what the disklabel says (2048).
(DOS, ISC, FreeBSD 2.0 see 2048 sec/cyl (64 hd, 32 sec/tr), 2089 cyl.)
Finally, I want to remark that it disappointed me that vidcontrol lets
one no longer select the shape of the cursor (FreeBSD-2.0: vidcontrol
-c 13.16) nor the screen saver (FreeBSD-2.0: vidcontrol -s fade)
On the other hand I like FreeBSD very much, since it makes a much more
reliable impression to me than LinuxWarelaris :-).
Please certify the receipt of this mail so that I'm sure it was read
before being sent to /dev/null and sorry for my English.
