Re: Questions about the openblocks AX3/4

Mr. Green,

Thanks for your kind reply.

I understand for detail and we'll be able to provide the product you
want when you get ready.

Basically we are so positive to offer our product to developers. Please
feel free to ask us if there's anything you want to know for more.

BTW we are now planning to prepare the application program for
developer's sample use. I'll let you know when it's figured out, hoping
it will help you all in the community.

That's the largest. Onboard 1GB plus additional SO-DIMM 2GB, total 3GB
is the maximum. Incidentally, we've confirmed that the 2GB or 4GB
SO-DIMM on 2RANK work. (It'll be 2GB RAM though you install 4GB hardware
on 2RANK.)

ARMADA XP has several revisions. The one we've adopted does not support
LPAE (Large Physical Address Extensions) thus AX3 cannot handle larger
module than 3GB.

SATA-2 300MB/sec, according to the spec sheet.
