Re: [coreboot] How to check if DRAM init is OK?
by ron minnich
it's an ARM. There was a primitive memory test in the early days of our ARM
ports that might be useful. It was simple but it caught our problems.

How about MemTest86? See this link http://www.coreboot.org/Memtest86, I
never use it before.

The ADL855PC is an embedded module that is using the i855GME chipset
(the same as the Getac W130 as far as I remember).
Last I checked, the 855 port was not very good, but there's probably
nothing in the way of attempting to write a port for that laptop.
You should make sure you have some means of recovering your flash chip
back to something working, because writing a port and getting a system
booting typically takes a few tries ;)

i855GM on laptop - possible or not?
by Andrey Korolyov
Hello,
I am trying to estimate amount of effort to make an old military Getac
to work with coreboot (currently it runs Insyde with computrace-style
code). All currently supported boards, lanner/em8510 and
digitallogic/adl855pc are desktops, which means that I should play
with EC support almost from scratch. Given the fact that i855G(M) was
quite popular in P-M era, are there any real issues standing behind
lack of support of a simular mobile platform in a tree?
Thanks in advance!
