I know that this image worked for me on various machines:

iso
Maybe you want to give it a try?
(A C3750 should work with it)

Yes, that should be able to boot.
(Note: The 64-bit debian 6.17 kernel has an issue right now, where it does=
n't boot for me though).

You need to build with "make ARCH=3Dparisc64" when building a 64-bit kerne=
l.
Make sure to have 64-bit hppa cross compiler installed.
If not, please let me know the errors you see.

"make ARCH=3Dparisc64 palo".
Then you should be able to remotely boot the kernel via TFTP.
