Gigabyte 6PXSV4 E5-2680 v2 7970 Unbootable After Install

[witchbutter]

I know the hardware I have is not the best in terms of compatibility but I had to give it a fighting try.

I am able to get 10.9.4 to install and boot once using -x PCIRootUID=0 flags. Then after running Multibeast and attempting to reboot I cannot get it to start.

A regular boot leads to a screen full of gibberish: (attached)

Trying to boot in single user mode leads to a very weird error about deadbeef:

Memory allocation error: Addr: 0xdeadbeef, Size: 0x0, File: ati.c, Line 1772

This is a non recoverable error! System HALTED!!!


This leads me to believe something is unique about the Radeon 7970s. Is there anyone that can help me interpret the error?

Again Search is your friend - Link.

Boot with maxmem=4096

This site has been around for a long time - Many problems have already been addressed.

Good Luck

Apparently I posted too soon, and had to be told to search more. /sigh I still don't really have an answer to what the error means, but thanks for pointing me at some other discussions.

For anyone else who might inadvertently read this, the gibberish error is apparently the standard problem with Radeon 7970. This board has on onboard Aspeed vga card that cannot be disabled, however it's not sufficient just that it is enabled but it must be told to boot first in bios.

Furthermore suggesting that the only way I can boot is to use maxmem=4096 is a lot like saying "you're hardware just won't work" because I am certainly not going to run mavericks with 4gb of memory.

You only have to boot with maxmem=4096 until you have run Multibeast, after that everything should be ok and you can boot without.


Good Luck

The gibberish is not important. The AMD Radeon 7970 must be the secondary graphics device in your system in order to boot using Chimera/Chameleon without a boot error and gibberish text. This is because of the larger video BIOS size. If that error continues you may have to use terminal to move the boot loader and the extra folder to the EFI partition.

You need to do this because the Xeon cpu you are using has no integrated graphics on the chip.

I attempted installing Mavericks with a system using this board and had no luck either. Maybe now I'll understand the errors better.

My Java Program converted 0xE0000000 to à 0000 0000 0000, 0xFBD00000 to ûÐ 0000 0000, and 0x0000E000 to 0000 0000 à 0000. As for 0xdeadbeef it converted it to Þ*¾ï. All of that was converted from the hex you supplied to ascii characters if that helps. I'm not sure if Endianness matters their either, but if it does I can do the conversion again if it helps. The conversion from binary to hex is done for you though. None of this may even matter though because the error makes no sense even when converted to asking if I'm doing the forensics correctly.
