No problem.

Describe the solution you'd like
The HP Falcon motherboard (HP-branded version of the MEB-VM) was used in several HP Pavilion machines from 1998-1999. It contains an Intel 440ZX-66 chipset, an SMsC FDC37M702 Super I/O, an Award BIOS ROM with an SST chip, support for 2 PCI slots, 1 ISA slot, and 1 AGP slot, and an integrated ATI Rage IIc AGP GPU.

Describe alternatives you've considered
No HP Pavilion motherboards are emulated at present.

Additional context

I have not been able to find a datasheet for the ATI Rage IIc; this will have to be implemented at a later date. Until then, any other AGP graphics card should do the trick, although the restore media for machines that used this board (including the 6475Z and the 6468) do not contain drivers for other graphics cards.
