OK, I do:

FreeBSD/alpha SRM disk boot, Revision 
(jkh@beast.cdrom.com, Wed Nov 25 16:13:25 GMT 1998)
Memory: 32768 k
/kernel data=0x1e3f40+0x26918 syms=[0x8+0x3f210+0x8+0x25192]
Please insert MFS root floppy and press enter:

So, now it wants the mfsfloppy. This comes out of boot.conf:

su-2.01# cat boot.conf 
@load /kernel
@echo Please insert MFS root floppy and press enter:
@read
@load -t mfs_root /mfsroot
@boot
su-2.01# 

So I insert the mfsroot floppy:

Please insert MFS root floppy and press enter:

load: can't find '/mfsroot'

Hit [Enter] to boot immediately, or any other key for command prompt.

What is it trying to tell me here? Floppy bad? Is the mfsroot.gz a simple
file on a UFS formatted floppy or is it dd-ed onto a floppy?
