Change the PCI-Device base address

Post by tjroamer »

Hi,
I need to install 2 virtual PCI devices in the VirtualBox. Each PCI-Device has 256MB memory which can be accessed from the driver. It failed to be loaded by VirtualBox, because the first PCI device was allocated by the WindowsXP from 0xF040_0000 - 0xF81F_FFFF. and the second device is out of the 4GB memory.
Is it possible to shift the base address of the 1st PCI-device to something like 0xE040_0000, such that the 2nd device has enough address space to be installed? thanks.

/Kai
