Any character-oriented terminal or VT100/IBM3151/WYSE60 etc emulator connected
via serial port 1 will do (even standard Windows terminal!). When machine starts
and displays E1F1 on the LCD, push '1' on the emulator/terminal to make it
current console and drop into firmware menus. If you have graphics adapter -
then you can use standard PS/2 keyboard and mouse and any Vesa/DDC compliant
monitor to be used as console / start X server when system starts; in this case
press F1 key on the keyboard when you see 'E1F1' on LCD. Get IBM GXT-130P
adapter (re-branded Matrox MG200), don't go with GXT-110 - it is not fully
compatible with X and causes crashes.
Note: to boot from CD, press '5' (on emulator) or F5 (on graphical console if
any) at 'E1F1' on LCD display to temporarily set CD as first device in boot
sequence. PXE network boot should work as well, but check your firmware level
from firmware or SP menu and upgrade to latest if necessary (www.ibm.com has all
firmwares available for download).

You should be fine installing Sarge, unless you have got any SCSI RAID
controller in H50 machine, they seem to be not reallyl supported on Powerpc
platform (although driver, called IPS, exists). I filed a bug about this issue
with kernel developers.
Standard F50/H50 SCSI controllers (SCSI-2, ULTRA-2 and ULTRA-3) based on LSI
chipset are working OK.

Th IS a CHRP machine, same as my 7025-F50 (they are very similar).

Be careful and patient with boot CD if you use stable distro rather than
development, it might not boot at first (wrong location of yaboot.conf file or
yaboot.conf recorded as YABOOT.CON on the CD). There are few articles on the
internet about modding the boot CD image to start properly on RS6000 machines.
I done modding myself according to articles and everything worked.
