I saw a few datasheets for embedded systems that have 2M or 4M | of flash. Some of that is for the BIOS, but part of it can be used | for a system image. That's a very common thin on other platforms as | well. Is this bits or bytes. The Intel firmware hub can have 4 or 8 Mbits that comes with any Intel 8XX system so with gzip you could fit a bunch of stuff in a standard off the shelf motherboard. Also CMOS memory is increasing and that could be used for some configuration info to be used as non-flash persistant storage such as IP address and such. Also having a small BIOS image like General Software would help save space. Doug A. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
