Your laptop is base on GL40 withou support of FSB=1066 Mhz. So you can't use your P8600.
T8100, T8300, T9300 and T9500 are recommended.

Thank you very much DeathBringer, you are the man   So now I will look for 800mhz CPU. THANKS!

Make DOS USB-stick (e.g, by Rufus)
Copy phlash16.exe and file with mod (JV50134m.WPH)
Boot into native DOS and run
phlash16 /x /s /c /mode=3 JV50134m.WPH

still works, thanks a lot.

Hi ! Kinda new here, absolutely flabbergasted that this thread is almost 15 years old and still somewhat active.

I recently upgraded from a T4500 to a T9300 (GL40 chipset, official BIOS v1.33) on my Acer Aspire 5738, but it doesn't seem to work out of the box. I can get to the BIOS and it shows that the CPU is correctly recognized, but i can't get my pc to boot to windows. It sort of "boot cycles" constantly. I tried booting into a bootable USB drive with the windows installation media in it, and it does show the windows logo for a split second but then it stops immediately and shows a black screen. Missing microcode maybe ?

Is there any way to help me ?

There you go ! I put back the T4500 in to take that screenshot (seems to confirm that the problem comes from the upgrade). Quick sidenote, i was surprised to see that the chipset isn't the GL40 but the GM45.

I think your T9300 is dead.

Indeed it was ! So quick question, i could go for a functionnal T9300 or T9500, but wouldn't it be technically possible to install an X9000 ? They can be found for cheap and they have an 800 Mhz FSB. If i beef up the cooler, do you think it could work ?
