Linuxbios on the EPIA, 9pccpu in the CF slot. takes 10-11 seconds to boot to a useful state (rc prompt) from ^T^Tr. It's amazing how nice it is to debug when the cycle is that short. This is way faster boot time than the geode cluster I had at usenix. And, I can speed it up a bit! Also, echo reboot 9pccpu > /dev/reboot is only 6 seconds. Also wonderful. So, this shows to me that you can have a 9pccpu in the EPIA in Compact Flash, and that 9pccpu makes a useful bootstrap, and even nicer, is faster than 9load to do the job. I have one thing I'd like to do, subject to someone telling me it's a bad idea. I'm thinking of writing a small C program that does the equivalent set of steps as the 'disk/fdisk -p blah blah ; disk/prep -p blah blah' that are currently done in scripts. This would make it so I could move nvram to the CF instead of CMOS. Comments? ron
