 |
|
hello everybody.
i have some trouble changing the configuration of my gentoo/alpha system.
currently the system has the following partitioning scheme on /dev/hda, which is the one and only harddisk in the system. | Code: | axp ~ # fdisk /dev/hda
Detected an OSF/1 disklabel on /dev/hda, entering disklabel mode.
BSD disklabel command (m for help): p
4 partitions:
# start end size fstype [fsize bsize cpg]
a: 3 15 13 ext2
b: 15 139 125 swap
c: 1 30515 30515 unused 0 0
d: 139 30514 30376 ext2
BSD disklabel command (m for help): q
axp ~ # |
where partition a is from where i boot, b is of course swap and d is my "/" partition.
now i want to do some crazy stuff.
i have a little adapter which connects a 512MB CF card to the ide bus. no matter if you know such a thing or not. it just acts as a normal harddisk.
so now i want to have the kernel on a little partition on that new device (/dev/hdb), boot from that, but the "/" partition should stay von /dev/hda4.
the partitioning scheme on the new device is the following: | Code: | axp ~ # fdisk /dev/hdb
Detected an OSF/1 disklabel on /dev/hdb, entering disklabel mode.
BSD disklabel command (m for help): p
3 partitions:
# start end size fstype [fsize bsize cpg]
a: 3 200 198 ext2
b: 201 992 792 ext2
c: 1 993 993 unused 0 0
BSD disklabel command (m for help): q
axp ~ # |
i mounted the partition /dev/hdb1 as /boot and copied my kernel and system.map to the new location.
no problems until here.
now to writing the bootloader. | Code: | axp ~ # swriteboot /dev/hdb /boot/vmlinux
error: bootcode overlaps with partition #1. If you really want this, use -f1
axp ~ # swriteboot -f1 /dev/hdb /boot/vmlinux
error: bootcode overlaps with partition #3. If you really want this, use -f3
axp ~ # swriteboot -f3 /dev/hdb /boot/vmlinux
error: bootcode overlaps with partition #1. If you really want this, use -f1
axp ~ # swriteboot -f1 -f3 /dev/hdb /boot/vmlinux
axp ~ # |
okay, so far so good.
but now: | Code: | axp ~ # abootconf /dev/hdb 1
abootconf: could not find aboot on disk /dev/hdb
axp ~ # |
and this is the point where i am stuck. what is the problem here?
at last swriteboot ran without an error. why is the bootloader not found? or is this a wrong error message?
i am happy with every idea you provide.
thanks in advance
