Re: RAID question
Hi Fredrik: Are you referring to BIGMEM or something else?

Re: 8G RAM on 32 bits
Thanks... I am downloading a recent snapshot and will try to do a clean install with the amd64. I will keep you posted.

Yes, I expect the same result from amd64.

It means you won't be able to use the disks at all while they're
still set in RAID mode in the BIOS, you need to have the BIOS present
them as standard disks (preferably AHCI).

Correct, with amd64 you can boot from RAID1 without an extra
non-RAID partition. It certainly works in -current, I'm fairly
sure it works in 5.1, but quite possibly not in 5.0.

Re: RAID question
Stuart: I think you're right (not hardware RAID).
http://ca.asus.com/en/Motherboards/Intel_Socket_1155/P8Z77M/#download
The download page for P8Z77M motherboard includes:
Intel(R) Rapid Storage Technology Driver Software V11.1.0.1006 for Windows
XP/7 32bit & 64bit.(WHQL)
Intel(R) AHCI/RAID Driver for Windows XP/7 32bit & 64bit.
This certainly suggests that a driver is required for RAID. After getting
RAID setup in BIOS; I boot from USB-connected (Samsung) drive and do not
see drives in dmesg.
BIOS: http://www.gallery.bax.on.ca/IMG-20120731-00835.jpg
dmesg: http://www.gallery.bax.on.ca/dmesg-P8Z77M-RAID.boot
This dmesg is from i386; shall I expect the same result from amd64? I will
try that later today.
Does your "not compatible" statement mean that I will need to boot from a
small non-RAID partition? The you provided seems to imply this is not
needed ("*the amd64 kernel allows booting directly from a softraid array.*
").

Re: 8G RAM on 32 bits
All i7's are 64bit compatible. If you can try a new kernel (bsd.rd should be enough), then you can try it out and see if it boots. If it does boot, it is highly recommended to do a clean install. While it is possible to upgrade from i386 to amd64 this is not recommended as it is easy to miss some bits and add some problems to your system.

Re: 8G RAM on 32 bits
Hi, thanks for the answer. This is a Sandybridge Mobile "Intel® Core™ i7-2640M CPU @ 2.80GHz × 4 " How can I find out whether this is 64 bit-capable? I have googled but not very successfully... I am afraid I am also newbie in the tech jargon...
