>Description:
The target host is a 486-33 with Adaptec 1542b scsi adapter,
ne2000 ethernet adapter and generic 1440 floppy drive. All worked 
well enough to install FreeBSD 5.1 with the gymnastics described here:
http://imlpld1.berkeley.edu/~bob/FreeBSD/ 

On booting the 5.2.1-RC floppies (fdformatted first, all md5 sums
are correct) written on the boot drive the usual prompts are
presented and the loader prompt invites device.hints: those
are 

set hint.aha.0.disabled=0
set hint.ed.0.disabled=0
set hint.ed.0.port=0x300
set hint.ed.0.irq=5

The changes are reflected (and unaffected by double quotes)
in the "show" command, but a "boot" command does not probe 
aha0 nor ed0, ending with the:
 
mountroot>

prompt which accepts
ufs:md0a
as a reply.

/stand/sysintall 
starts up, with a flock of errors related to failed module loads and
an invitation to use the driver floppy.

The sysinstall Main Menu comes up, but with no disks nor ethernet
adapters found it's a fruitless venture.



>How-To-Repeat:
Try to reinstall again.

>Fix:
None at this time.
