First post here, so please be patient :-)
I have followed this guide by joshhh and now have a working T510 (4313-CTO) with 10.8.3. Everything is working except for wireless. I have purchased a Broadcom mini-pci card to use for wireless, but without flashing the BIOS I cannot install it.
Since my system is now OS X only now, I wanted to flash the BIOS back to the version joshhh has posted. However I cannot find a DOS tool to flash the bios. What and where can I find a program to do this? I have hunted the forums, however most people seem to boot into windows to load the bios, which I can't do. I can boot Ubuntu linux or DOS.
Can someone please point me in the right direction?

Thanks.

Hay,  What do you think about looking at how the displays are configured?   I ask because I've been trying to get a K3000m in a Dell M6700 working.  I've experienced much the same as you. However I've found that the internal LCD works, and with CE/CI, but the backlight is off.  I can connect using desktop sharing and see in ioreg that the card is initialized and working.  I can also change resolutions.  So it's getting the internal LCD's EDID okay.

However when I connect an external display on any port it hangs the graphics system(I can still SSH in).
I also read that Kepler cards for the first time support 4 displays simultaneously.  This implies some changes in the way the displays are connected and defined.  Could it be that different things need to be injected for this new setup?   One anomaly I noticed on the M6700, all the 4 displays have a 'port-number' property set to 9.  Looking at the ioreg from an nvidia retina mac.  It's port-numbers are 0, 1, 2, 3. If this is the 'port' in the same meaning as with Intel HD graphics.  There is no way they should be the same.

@joshhh  - I have tested some of the vga bioses that you´ve uploaded but chameleon says: the bios file is too big to load, and then I extracted mine and the size is 64k and yours are about 90k, there´s a way to force chameleon to load it in another addres of the memory ? Or a way to downzise it ? Because I think this is the way to make our Mobile Kepler working on a hackintosh !

Thanks in advance.
