Netbackup boot CD

I have been trying to deploy netbackup on IBM blade servers. The OS is RHEL3 AS8. The boot cd is created by netbackup itself using linux cd's. The issue is when I try to boot up with the cd, the KVM switch of the Blae center hangs and does not respond. I have been searching around for some kind of resolution and came up with one possible answer. I need to add 'usb-handoff' as a boot parameter.
Is it possible to modify the boot loader of a boot cd and pass additional boot parameters? A quick response would be much appreciated.
