Booting from SCSI device/no boot ROM

Booting from SCSI device/no boot ROM

Post by Georg Bauha » Sun, 29 Mar 1998 04:00:00



Hi,
can s.o. give me advice on how to boot NetBSD i386
when there is no IDE drive attached to the machine
and when the SCSI adaptor (Adaptex 152...)
does not have boot ROM? The system files have been
placed in partitions on /dev/sd1x. Booting from
floppy would be fine.
Or is there anything in the docs?

for your initial boot, boot from floppy, give the kernel the "-b" run-time
option, and tell it to use sd1a when it asks.

Then change the kernel configuration file, replacing

config          netbsd  root on ? type ?

to

config         netbsd  root on sd1a type ffs

and build a new kernel; this one will be hardwired to booting from the
disk partition.

(Be sure to have a floppy with a GENERIC kernel around for emergencies).

1. diskless boot hit error while booting kernel, cannot find boot device, dhcp problem?

Hi people, wonder if you could help me on this:

i have two redhat 7.1 machine, one trying to boot off the other
through etherboot. Everythign goes fine, the client boots, retreat the
kernel off the server through tftp, and starting the kernel. Then it
stopped with error messages:
.
.
VFS: Cannot open root device "nfs" or 00:ff
please append a correct "root=" boot option
Kernel panic:VFS: Unable to mount root fs on 00:ff

kdb >
.
.
Where do I append a "root=" option? is it a dhcp problem? in
/etc/dhcpd.conf, i did put in

 option root-path "/boothome";

along with the other options. also, when tagging the kernel image, i
also have rootdir option:
mknbi-linux zImage --output=kernel --rootdir=/boothome

nfs export is correct, i have no idea where i did wrong.

any clue?

thanks in advance.
