[Etherboot-developers] Bootrom hang at booting local - any ideas?

[Richard C. <csh...@ds...>]

Folks, I have a bootrom which cannot boot the local
system. It hangs completely after
pressing "L". Network boot works fine and floppy boot works 
(both "N" and "L").

System: Etherboot 5.0.4 and an epic100 card (SMC EtherPower II/10/100) with
a 512kbit flash memory chip (I couldn't find anything smaller -
did you know that small size flash memories <= 256kbits seem
to be endangered species?) I'm pretty sure it doesn't clash with
anything else in himem as I removed all other cards.

I get the message

ROM segment 0xca80 length 0x5800 reloc 0x94000

If I press "N" it works, "L" justs hangs the system.
Any idea how to debug why this isn't working?
BTW using a floppy I get

ROM segment 0x8000 length 0x4000 reloc 0x94000

and both "N" and "L" work.

Strange that the lengths are different (0x4000->0x5800). 
The bootrom is burned using epic100.rom (16384 bytes)
exactly as created.

P.S. Who sells 256kbit/128kbit 32DIP flash memory?
