Ooh, cool. This is crucial when you want to do a persistent 'failed' state for cheap machines with memory errors that you are using as appliances. Can you MFC these?
peter 2007-06-15 22:58:14 UTC FreeBSD src repository Modified files: sys/i386/isa clock.c sys/amd64/isa clock.c Log: Prototype (but functional) Linux-ish /dev/nvram interface to the extra 114 bytes of cmos ram in the PC clock chip. The big difference between this and the Linux version is that we do not recalculate the checksums for bytes 16..31. We use this at work when cloning identical machines - we can copy the bios settings as well. Reading /dev/nvram gives 114 bytes of data but you can seek/read/write whichever bytes you like. Yes, this is a "foot, gun, fire!" type of device. Revision Changes Path 1.232 +99 -0 src/sys/amd64/isa/clock.c 1.237 +99 -0 src/sys/i386/isa/clock.c
