Optiplex GX520 & Debian Wheezey blue then black screen on boot
Ladies & Gents,
I have a small problem. I have acquired a Dell Optiplex GX520 (desktop) to replace an older p4 desktop (mini tower). The only live cd I can get to boot (default) is an old Cluster Knoppix disk that is running the 2.4 kernel, but it does not function very well. I was able to get the latest gparted live cd to boot using the manual setup and the vesa driver. Every other driver yields a blue screen that then goes black after the monitor gives up.
I did get Debian Wheezey (net install i-386) to install finally from the ncurses install but I am unable to boot the machine, even in single user mode and still be able to see anything except the blue-to-black screen.
The Optiplex GX520 has an "Intel GMA 950 Dynamic Video Memory Technology 3.0" according to the Dell specs.
So far google has not been much help.
I have passed vga=791 and vga=772 to the kernel with the same results.
There is no video or vga entry in the default boot line in grub2 just ro and quiet.
What should I pass to the kernel from grub2 to get it to boot so I can see it?
Also is there something I can change in the bios that would help? Seams not. I updated it to the most recent version from Dell with no joy. I still can't get any kind of boot that I can see after the, I think frame buffer, activates. At this point I don't know what to check.
