OK, I fixed the problem with alpha1, by upgrading its firmware from 3.2 to
7.0 and now it has no problem using BOOTP.

 In order for me to upgrade alpha1's firmware, I had to place the
m500_v7_0.btp file
on to tape with the mkbootfirm utility on another DEC 3000 system running
DEC Unix.

    cp m500_v7_0.btp fwupdate.exe
    ./mkbootfirm fwupdate.exe | /usr/bin/dd of=/dev/rmt0h bs=512

    This command is used to place the firmware on to a floppy.
    ./mkbootfirm fwupdate.exe | dd of=/dev/rfd0c bs=64k

Then, swap that tape drive into alpha1 and boot the system from the firmware
tape.

I have given up on this problem with alpha2, I have no ideal as to why it
doesn't respond to the serial consoles keyboard.

fixed this problem by issuing the following at the SRM prompt:

>>> set server on
