does anyone have the full 3.30 BIOS for a Satellite P100-106 PPAAE Laptop ?

Thanks but when you look at the applicable models it does not list a P100-106 PPAAE I didnt really want to risk using these if my model is not listed.
I am really surprised no one has archived older BIOS for Toshiba laptops as I have had no issues getting older ones for other laptops ie Acer.
Toshiba only makes one motherboard for all the P100/P105 series. They just don't list European models on the U.S. site and vice versa.
From a tech support point of view, Toshiba only wants people using the latest...I can sympathize with that. But the files are still available provided you know the filenames...which is what I linked to above.
What exactly are you trying to do with such an old BIOS anyway? The ACPI DSDT GPU fan issues were fixed in v4.70 and v4.80 *apparently* only enables Intel VT option if your CPU supports it.
The fan keeps cycling at full speed on/off every 15-20 seconds, its very annoying. I have tried everything I can think of and find in the forums to solve it.
The laptop came with 3.30 but I cant remember whether the fan did the same thing with that BIOS, its currently on 4.80 as I upgraded it when I got the laptop, I want to take it back to 3.30 to see if it does the same thing.
So are you saying Sp100v33.exe should take my laptop back to 3.30 despite not listing the model and not "brick it" ?
(additional, just took the plunge and tried the Sp100v33.exe on my UK P100-160 and it worked fine, let me downgrade the BIOS)
tried 3.30 BIOS and it still does it where the fan comes on full for a second then reduces again. Tried a few of the others and same there too.
yes I would be willing to try a ACPI mod.
Not sure if I'll have time tonight, but maybe tomorrow night I'll take a look.
Couple of questions for you:
1. What OS are you trying to use (XP, Vista, or 7, or Linux)?
2. Could you flash the stock 4.80 BIOS and upload an RW-Everything ACPI report?
I am using Windows 7 32 bit

thanks for those I will test the DSDT mod later today.
Right I have tried the DSDT BIOS. If the Toshiba power options in Windows are set to Maximum Performance and the BIOS Thermal control is set to performance - no difference fan still goes full speed then silent.
If I set Toshiba Power options to Battery Optimised in Windows I have noticed on next reboot the BIOS Thermal control has changed from performance to silent, so it seems the change in OS also changes the state in the BIOS. It did not do this before on the original 4.80.
However the fan still cycles full/low every so often as before so it does not seem to have made any difference to that.
Other thing I have noticed is the Process Power Management works. If I set it to Min/Max CPU 100% it does actually run at 1.6ghz, and if I set min to 50% and max 100% it runs at 800mhz to 1.6ghz depending on load. It don't think it did this before.
Thanks for testing. I'll see if I can figure out the thermal tables...maybe check back in a few days.
okay thanks very much for your help so far. Much appreciated.
Sounds like lazy Toshiba to me and something they wont fix.
Here are the two tables you have asked for.

LOL...it's always the lazy OEM's...or the 3rd party that they outsource to.
Both files are exactly the same. Perhaps that only affects non-full ACPI operating systems.
I don't have time now, but maybe later tonight I'll update the ACPI to have the values that are in that PDF document (Figure 2). I also want to look at those other params (_TSP, _TC1, _TC2) and see if they're sane values too. I don't mind doing a little trial to see what values seem suitable for you.
BTW, specifically what CPU do you have?...I know my mom's laptop has a T5500.
Surprise surprise the same.
Its a T5200 1.6ghz 533mhz FSB.
Thats strange because the UK spec for the P100-160 says it only has a 533mhz FSB. I tried to use a T5750 2ghz 667mhz FSB CPU in it but it refused to boot.
so that could be why its not working the CPU comparison table I used said something like socket 479 or something like that.
Just fitted a new fan to the laptop to see if that makes any difference although whilst I am typing this (on my PC) just heard it whirr on full then off twice.
okay will do thanks again.
