I'm trying to install Debian Sarge on a 7025-6F1 (dual processor RS64-IV
with 53C896 scsi controller) but on kernel loading the server hangs at

returning from prom_init

while the LCD on the front panel says "E105"

A search with google reveals that probably I need a custom kernel for my
machine. Anybody knows where I can find the right kernel?

TIA,
Michele
