There are quite a few BIOSes for the 6450, maybe you can find a match here: Video Bios Collection | techPowerUp Another way is to extract the BIOS directly from your card.

I got my ATI Radeon HD 2400 XT working with the open source drivers in Ubuntu 13.10. Had to extract the cards BIOS and save it as "/lib/firmware/radeon/vbios.bin" (can't be done in a VM). Next step is to download the Linux kernel and apply this patch: https://bugs.freedesktop.org/show_bug.cgi?id=26891, then compile and install (it's not necessary to make changes to the default configuration). Add "blacklist vmwgfx" to the end of " /etc/modprobe.d/blacklist.conf" to disable the driver for the VMWare video card. Last step is to restart the VM and hope the monitor wakes up. Got the idea from this article: Debian on the MacBookPro8,2 Edit: I have also tested an AMD Radeon HD 7970 and an AMD Radeon HD 6450 with success. Both have working VDPAU support with the open source drivers.
For accessing more RAM while using GPU-passthrough you can use the "pciHole.start = 1200" and "pciHole.end = 2200" options (works for me and many others). I have successfully passed my Radeon HD...

For accessing more RAM while using GPU-passthrough you can use the "pciHole.start = 1200" and "pciHole.end = 2200" options (works for me and many others). I have successfully passed my Radeon HD6450 to Ubuntu (12.04, 12.10 and 13.04) using Catalyst drivers, Windows 7 (also had to install the VMware driver along with the Catalyst driver) and OSX 10.8.3 (using unofficial hack/patch) on ESXi 5.0. For sound I'm using a Terratec AureonDualUSB on an USB-controller on PCI-passthrough. Config is: ASRock X58 Xtreme (bios 2.90) Intel Xeon E5606 24GB of some DDR3 ECC Club 3D Radeon HD 6450 1GB (on passthrough, showing as "Unknown VGA compatible controller") Gigabyte Radeon HD 2400 XT (on passthrough, tested with Windows 7 and Ubuntu 12.04) IBM M1015 in HBA mode (on passthrough) with 8x 2TB Seagate disks (for my fileserver VM) Crucial M4 128GB (for VM's) Crucial C300 64GB (for VM's and ESXi hypervisor) Creative X-Fi PCI (on passthrough, only tested with Ubuntu)

Install VMware Tools, reboot and then shut down. Configure your 6750 for passthrough. Boot Windows into safe mode, then open Device Manager and disable your 6750. Reboot. Install Catalyst, a reboot may be needed. When you get picture on the screen connected to the 6750 you can open "Screen Resolution" (as it's called in Windows 7). Make the screen connected to the 6750 your primary screen, then you can disable your VMware screen. Configure the pcihole options if you want to use more than 2816MB RAM (2304MB two GPUs inn passthrough to the same guest and 1792MB with three) in your guest os running with the 6750.
