Toshiba L305-S5894 Intel GM4500M VBIOS

[tazodie]

Hello all!

I've tried repeatedly to replace the stock Intel GM4500M Vbios in this Toshiba L305-S5894 with the updated replacement VBIOS that comes with the Intel Drivers using Phoenix-Mod-Tool and Slic, I've extracted the vbios and hexed the new one in and it just black screens and I have to go to recovery. Strangely it appears as if there are two seperate copies of the vbios contained in the bios file?

Any help would be greatly appreciated.

I can supply all files that I have currently.
Included in VBIOS_MOD.zip

The original bios file: ps10220m.fd
The updated VBIOS from Intel: vbios_gm4x.zip (ctg_2107.dat is vbios)
Toshiba SLIC21: Toshiba[TOSINV-TOSINV00-INV]2.1.BIN
Toshiba SLP: TOSHIBA.txt
Toshiba Certificate: TOSINV00-TOSINV-2.1.XRM-MS
2 Intel Roms Extracted from original bios with Phoenix Mod Tool:
8DFAE5D4-B50E-4C10-96E6-F2C266CACBB6.MOD
86430990-055C-474B-A4B4-6C9A29BFA14F.MOD

Also would it be possible to merge updated vbios with this modded bios:
Tosh_L305_UlkMenus_ByCamiloml.zip

I don't know if i'm missing something but if i open this bios with h20eze and export the two oproms that relate to vbios they are are still as follows

the original, the exported and the ones labelled as .mod all show

Build Number: 1625 without HDMI PC 14.34  04/02/2008
Build Number: 1625 with HDMI PC 14.34  04/02/2008

the .mod ones do have a dozen or so characters at the very start that are different but otherwise look at a glance to be the same.

ctg_2107.dat contains Build Number: 2107 PC 14.34 01/25/2011 18:25:56 and looks completely different compared to the others.
