- Hello everybody, (and a big thanx to the Jolitz'ses !)
-
- Machine: 486 33 Mhz AMI bios 8Mb RAM 256 cache. (UM 82C480 Chipset)
- (all funny configurations tried: no difference).
-
- Disk: Western Digital AP4200 "Piranha" IDE
- 1263 cyl, 8 heads, 41 sect.
-
- The bios is set to the true params, on the variable disktype 47,
- (stored either at 0:300 or 640K-1k, makes no diff).
-
- If I use the complete disk for 386BSD things work, if I have one or two
- dos partitions (3.30, don't ask, I'm forced to !) I cannot boot from the
- harddisk, the dist.fs and fixit.fs boots OK and finds the harddisk without
- problems. But when I boot from the "install"'ed hard-disk the result
- is this:
-
- ...
- wd0 <WDC AP4200> at 0x1f0 irq 14 on isa
- ...
- wd0: cannot find label (no disk label)
- panic: cannot mount root
-
- The machine did run 0.0 sans problems.
-
- Anybody know what's wrong ?
-
- Could this be related to the BIOS-params being in RAM instead of EPROM ?
- As far as I have checked the boot, the params are indeed copied up below
- 640K, but could it be too late at that time if the params are in RAM ?
-
- Is there any way I can turn on debugging to find out what's going on ?
-
- How about a debug.fs distribution in which all possible (relevant) debuging
- was turned on to debug boot-problems... ?
-
- summary of combinations tried:
-
- BIOS param dos part 386bsd Status
- 1024 cyl none whole disk OK
- 1263 cyl none whole disk OK
- 1263 cyl 199 cyl rest of disk hangs early in boot with fs+hd
- (32636 kb) lights active, before any text
- has been put on the video
- 1263 cyl 100 cyl rest of disk Panics as descr. above
- 1263 cyl 10 cyl rest of disk Panics as descr. above
