Hi, folks.
While booting 6.1-RELEASE-p6 i have this error on /boot/loader stage:
can't load kernel
ls shows nothing...
lsdev shows me:
disk devices:
disk0: BIOS drive C:
disk0s1: FFS bad disklabel
But when i am booting from LiveCD i see all my labels, i can mount them,
i can produce read/write operations.
Other thing that confused me is that when i am using second stage
bootstrap file i see my root partition:
FreeBSD/i386 BOOT
Default: 0:ad(0,a)/boot/loader
boot: ?. .. .snap bin boot dev etc lib libexec mnt proc and so on...
But when i am trying to boot kernel (GENERIC) directly from bootstrap
i have "BTX halted" error, don't know if this actually supported.
World was builded on other box and installed to this drive
using tar.
Here is additional information that i can get from LiveCD:
root@ccv:~# fdisk /dev/ad0
******* Working on device /dev/ad0 *******
parameters extracted from in-core disklabel are:
cylinders=19679 heads=16 sectors/track=255 (4080 blks/cyl)
Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=19679 heads=16 sectors/track=255 (4080 blks/cyl)
Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
