Hello Jim
Thank you for the tips. I will have a look into it. Would be nice if
QEMU could allow us to enable write access to the BIOS memory range
(shadow RAM) which isn't in use.

Hello
What does I need to change in the source code of QEMU that it would be
possible to enable write access to the ROM adresses from 0xC800 up to
0xEFFF ? For instance, "UMBPCI.SYS"
(http://www.uwe-sieber.de/umbpci_e.html) can made this range
accessible for direct access if no BIOS-ROM is using it. The original
chipset which QEMU emulate (Intel 440FX) does allow this, but in QEMU,
it won't work.
Any ideas ?
Andreas
I'd recommend looking at i440fx_init() in hw/pci.c as a starting point.
Also see if you can modify the constant IO_MEM_ROM.
