I'd like to for various reasons, one being In EPSILON you need to edit the /sys/compile/<your-kernel>/Makefile to change the load address from FE000000 to FE100000. In RELEASE (not yet released :-), you can config your kernel at such an address with the 'at' directive, I.E.: config "386bsd" at 0xFE100000 root on sd0 swap on sd0 >on how to build such a beast. I'd like to for various reasons, one being >I'd like to be able to put MORE than 16Mb of ram on my machine.
