yes, thanks that works well enough :-)

the only real problem is that smp kernel fails to boot with a ton of symbol errors
and cannot find sda3. there is a /lib/modules directory for the smp kernel. i wonder
if the smp kernel has left out the driver (symbios drive) for the scsi card?

its a good thing you cautioned me to leave a directive to the old kernel :)
