Older, smaller SCSI disks are really cheap on ebay these days, if
the fried disk is the main reason for using netboot.

I don't have 1.6 sources lying around any longer, but in 2.0 the
GENERIC kernel can boot diskless. But the only protocol it speaks
to get boot information is BOOTP. It no longer uses the obsolete
rarp/bootparam. Since the HP prom doesn't use rarp, either (but
HP's proprietary rboot protocol), this is not really a loss.

dhcpd can answer bootp requests. I haven't tried very recently,
but I have booted 2.0_BETA and 2.0_RCn snapshots via network on my
HP9000/425s.
