How much RAM is required?
Watch this: $ qemu-system-x86_64 -nodefaults -vnc :0 -monitor stdio -m 16k QEMU 1.1.50 monitor - type 'help' for more information (qemu) qemu: fatal: Trying to execute code outside RAM or ROM at 0x0000000000004000 Admittedly a silly thing to try. I don't really expect SeaBIOS to work with 16KiB of RAM. But I'm curious: how much does it require?
Interesting question. No idea. Try giving it more memory until it doesn't crash then you'll eventually find out. :) On Wed, Aug 8, 2012 at 1:50 PM, Markus Armbruster <armbru@redhat.com> wrote:

SeaBIOS requires a minimum of 1Meg of ram. I didn't even know one could request less than 1meg of ram from QEMU. -Kevin

I'll cook up a QEMU patch to give it at least that much. Thanks!
But QEMU may use other firmware/payload than SeaBIOS which might require less than 1 MB of RAM. On Thu, Aug 9, 2012 at 10:15 AM, Markus Armbruster <armbru@redhat.com> wrote:
