Have you looked into runimage? I have used runimage with ASU Tool to set
CMOS and I have also used it to flash There is a Document on sourceforge.
Its quite simple to set up under xcat.

Subject: [xcat-user] Netbooting off a floppy or CD image.
The following pxe boot file will boot a FreeDOS floppy disk image that
runs a CMOS utility (after memdisk and the image file are copied to
/tftpboot):
[root@drdxcatmn1 xcat]# cat /tftpboot/pxelinux.cfg/develkv8
#run CMOS utility on FreeDOS
DEFAULT Floppy
LABEL Floppy
LINUX memdisk
APPEND initrd=xcat/floppy/cmos-settings.img
IPAPPEND 2
Is there a way to have xCAT generate a similar pxe file when needed? Say
when a “nodeset host netboot=smcmos” is run?
It looks like the boottarget table can help, but I may not be setting it
up correctly because “nodeset host netboot=smcmos” generates a missing
kernel error.
[root@drdxcatmn1 xcat]# tabdump boottarget
#bprofile,kernel,initrd,kcmdline,comments,disable
"smcmos","memdisk","xcat/floppy/cmos-settings.img",,,
[root@drdxcatmn1 xcat]# nodeset develkv8 netboot=smcmos
Error: Did you run "genimage" before running "packimage"? kernel cannot be
found
Error: Some nodes failed to set up netboot resources, aborting
Also tried copying /tftpboot/memdisk to
/tftpboot/xcat/netboot/smcmos/memdisk, but no help.
Any suggestions?
Thanks,
Goran
