I have successfully booted NetBSD on a DEC 3000/500.  In the beginning I was
having problems because of out of date SRM firmware.  The problems that your
experience seem similar.

This page advises you to make sure you have the latest SRM firmware:
http://www.netbsd.org/Documentation/network/netboot/intro.alpha.html

Which is available from:
http://ftp.digital.com/pub/DEC/Alpha/firmware/readmes/dec3000.html

All you need to do, is download the m300_v7_0.btp in to your /tftpboot
directory.  Set up bootp & tftp on the linux server.

Then boot your Alpha server with 'boot ez0' and update & verify your
firmware installation. Re-boot the alpha.

Then continue following the Diskless booting procedure.

NOTE: if it still will not load the firmware via bootp, then you need to
create a firmware installation floppy, or tape.
