Hello,
I have the same problem: I want to use a 19'' widescreen monitor at a resolution of 1440x900 on my old laptop. The original LCD is broken and I removed it.
My laptop is the same of Zenith, an ASUS A2500H with:
VGA compatible controller: Silicon Integrated Systems [SiS] 65x/M650/740 PCI/AGP VGA Display Adapter.
Can someone send me the patched bios?
Thanks!
