Excelent.
I believe I have the fix for your "not booting" problem. Please try to
remove the block of code in sys/pci/ai7870.c that begins with the comment:
/*
* Ensure that we are using good values for the PCI burst size
* and latency timer.
*/
Even if it doesn't fix your problem, it should be removed. I'm still
looking through later revisions of the driver to find the second problem.
Thanks again!
