G75VW Deep Bios Help

[Dreamonic]

You ended up using the ASUS VBIOS with your G73SW GPU upgrade didn't you? Even though the GPU you used was that of another manufacturer because it allowed it to boot with the best results.

The G73's use OROMs though. The card you purchased, a standard MXM 3.0b GPU obviously had the other manufacturer VBIOS onboard. So I suppose these two mods are similar in that, yours was in fact OROM supported initially (G73SW) but used the onboard VBIOS in the end with a GPU manufacturer other than with the ASUS MXM GPUs but with their VBIOS?

I see what you're referring to now, ASUS GPU HW could be the problem with the upgrade in another system.

At this point im willing to try anything as long as its not permanent fail or have a fail safe.
As far as soldering, im pretty good but that bios chip is Tiny. Micro soldering at a whole new level and I dont have that kind of equipment or skill.
both cards are MXM 3.0 and have exact same pin layouts.

Just thinking here, but is it maybe possible to modify this card via hardware? hook it up externally to a desktop and have read/write access?
how can I go about stopping/bypassing (shorting) the vbios on the 780m?

To bad I cant find an Asus hardware specialist to diagnose this issue. compare the two builds and be able to specify.
I get it, Asus doesn't want you upgrading, they rather make money and you buy a new PC. Much more fun and satisfying to get something working in something where it doesn't belong

That kind of adapter actually exists (cool). No mention whether or not it works though with multiple vendors: http://www.pcidv.com/products.asp?id=628

To short temporarily, follow what I did in the picture below. You'll want to flash back to the M660780.ROM before doing so. Hopefully once it's temporarily disabled (bypassed) it may allow the OROM to be initialized. I'd recommend to use something of similar thickness of the pins used with the BIOS chip. Only touch the two pins in the diagram and those pins only! Do so before powering up with the AC adapter disconnected. Once those pins are bridged (keep it like that for the duration of the test) then plug AC adapter back in and power on the system.

Ill give it a go and see. hoping for the best. May the GPU gods be in my favor, lol

bread tie wire cut and bent to size. Was a touch to thick to fit between the chip and wire, so I crimped down with some tweezers and took a metal grinding disk and shaved off by hand. Did both sides. Lined up to the chip and snugged it in with a razor blade.
Now comes the real test. swap and boot.

DUDE!!!!! You are what I call a Fu**king GODSEND!! G75VW with GTX 780M Booted into Windows Success!!!!!!!!!!!!!!!
Major break though and accomplishment! Thank you all for coming to the show

So is this bridge something I should make permanent now that it is required for boot? I believe I should be able to solder those 2 points since Ill have room because its on the end.
Now im going to finish up the heatsink plate, get this thing down with some Gelid extreme and get some custom drivers booted.
