I've learned from the vbios guys that the term for
this is "POSTed."

In response to scitech softs request about getting the
emu into the kernel Paulo Marques did some work on
reducing the size of x86emu by reworking a lot of the
instruction calls to be multi-function and removed a
lot of duplicate code. He felt that with some more
work it would be possible to get the emulator down to
All that in 1M should be possible. I was able to get
General Sofware's bios + kernel + initrd in 1M on our
last board and that setup contained kexec,
TCPIP,ext2,pcmcia,ornoicoo drivers and a minium set of
pcmcia tools compiled with uclibc. I think I topped
out at 960k.
