That one is simple: you're booting in either monochrome or VESA mode,
because there's no native accelerated driver for the videocard QEMU
emulates, and BeOS does indeed use 100% CPU in this case. I don't know
what are the details under the hood, but this is a known fact.

You could try compiling QEMU with MingW instead of cygwin, as it
should work out of the box and the toolchain setup is not as
complicated or lenghty.


cheers,
