[Qemu-devel] Writing to ROM-Range 0xC800-EFFF

[Andreas Bollhalder]

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 ?
