Hi folks!

I've just installed OpenBSD 3.8 on my IBM ThinkPad 701C by booting up
from the floppyC38.tgz image. The 516 MB disk was partitioned with root,
swap, usr, var and tmp all meeting the minimum size requirements. I've
only installed "bsd", "base38.tgz", "etc38.tgz" and "man38.tgz".

There are 12 MB of RAM available. 4 MB on board and additional 8
MB installed separately. After the installation was complete I
received the following startup log:

OpenBSD 3.8 (GENERIC) #138: Sat Sept 10 15:41:37 MDT 2005

Maybe these information might help too:

(Boot from floppyC38.tgz)

boot> machine memory
Region 0: type 1 at 0x0 for 639KB
Region 1: type 1 at 0x100000 for 11264KB

Total free memory: 11903KB


I read about the RAM problem on old Compaq Armada notebooks (as
mentioned on OpenBSD.org). It's probably a similar error but I don't
know how to adjust the parameters to fit my RAM size. The Compaq example
relates to 64 MB RAM.

Any suggestions?
