Hi all,
Just want to confirm where we are in terms of things working or not.
The new system-agent binary works and recognises all 4 GB of RAM as
long as an additional pei data field is added to Stefan's patches in
http://review.coreboot.org/#/c/3831/ as detailed by Kyösti in the
comments.
The patches in http://review.coreboot.org/#/c/3830/ don't appear to do
anything for mrc.cache (it's still zero size) and this (or perhaps
something else) results in a time to SeaBIOS prompt of between 5 to 9
seconds.
I added a 64 GB SSD this afternoon, which I have working, but something
strange went on with geometry - if I tried to dd the partition itself
back it would crap out at 2 GB (this was after dd'ing the backed up mbr
onto the new drive). If I dd'ed the whole device it worked, but the
partition wouldn't mount, and fdisk would report that the partition was
too large for the device. Luckily, after reboot, it worked anyway. :)
Summary: if we could get rid of the 5 to 9 second delay, and just
confirm the drive detection geometry is A1 I think we are there.
John.
