[Toshiba Satellite A300-1ED] [CPU Upgrade] [BIOS MOD]

[ellie098]

Toshiba Satellite A300-1ED BIOS MOD need help.

I upgraded original CPU (T2390) to new (Q9100). 
I know chipset GM965 doesn't support 1066 MHZ FSB, but I did BSELMOD for force that CPU with 800 MHZ FSB, but only think I see is a black screen. The BIOS doesn't start. Before BSELMOD motherboard start and stop after few seconds, now it start and it's black screen all time. 
I think the BIOS doesn't support that CPU and if someone can add microcode for that CPU into my BIOS, I will be happy. Second opttion is force flash BIOS from newer version of Toshiba Satellite A300, but when I try that I saw from InsydeFlash "That BIOS is not for your notebook PC". It should work with that laptop, because specifications are very simillar, but I can't force to flash that BIOS. 

My actual BIOS version:
1.80 http://support1.toshiba-tro.de/tedd-file...135248.zip

BIOS that I try flash and I can't. 
2.20 http://support1.toshiba-tro.de/tedd-file...083938.zip

CPU old: https://ark.intel.com/products/35153/Int...33-MHz-FSB
CPU new: https://ark.intel.com/products/37033/Int...66-MHz-FSB

A few motherboards with Socket P (even with PM45 chipset) can boot quad cores CPUs. It's hardware incompatibility.
But you can try the motherboard's mod for quad core CPU supporting:

I try it and it doesn't work. 
There is NO WAY to run Q9100 in TOSHIBA SATELLITE A300-1ED (PSAG4E)
