Dear Debian-Mips
Developers: I’m in the
process of writing a sibyl boot loader image to a compactflash device for use with
a BCM91480b evaluation board, and I’d like to ask for assistance
regarding an issue I’m facing with the installboot command. I have
a compactflash card with two partitions, a sibyl boot partition and a partition
for the root filesystem. The results of the fdisk command are as follows
for the compactflash device. bcm91250a:~# fdisk /dev/hdb Command (m for help): p Disk /dev/hdb: 1024 MB,
1024966656 bytes 255 heads, 63 sectors/track,

the sibyl boot loader is correct, I’ve been using the sibyl boot loader
from the Debian installation on a BCM91250a evaluation system. The results
of the installboot command are as follows. bcm91250a:/usr/sbin#
