Hey Guys,

I have a toshiba p100-434 that i tried updating the bios of, but, i must have used the wrong one as now the thing won't POST.

It switches on but thats as far as it gets, nothing more.

Anyone got any advice on how to restore the bios in this situation?

Thanks

Hi Guys,

Sorry for digging this one up again but have either of you tried VoodooHDA solution?

I've got a (not so) nice kernel panic but maybe you would have more luck...

VoodooHDA.kext is a port of FreeBSD's kernel module for most (all?) HDA chipsets. One of which is our "beloved" Conexant HDA (Waikiki/Venice/...). I had a look at the code and it seems to support them so give it a go and share your experience.

Cheers,
mentorek

Hello to all the OSx86 community and especially all fellow Toshiba owners.

Finally I've got sound on my P100-324 with a self patched DSDT (following all the great tutorials here and in the Ubuntu topic from the Linux community).


I didn't remove any parts of the DSDT because I wasn't sure what all these while loops where for.
Instead I just moved the variable declaration outside the while scope and reset the value of the variable to 0 (0x00) inside the while loop.

Every modification as suggested in the Ubuntu topic was applied (name conventions and all other replacement was done).

I'm attaching the compiled dsdt as well as the non-compiled dsdt that was used.

Now I only need to fix the USB work without needing to disable the second core....

Hi. I also have troubles with my Toshi P-100-257... I can't restore original BIOS (the DMI part) anymore. If You find the way to restore it, please let me know.

With great respect, jazzminos.

Modified BIOS to try and activate the Conexant sound chips in models of the Toshiba P10x series

Thanks! I patched my P100 PSP MA502C and now the GPU fan stays on and my laptop stays cool. Still working on trying to get the audio to work though!

Hi guys,

I've been trying to get our beloved soundchip to work for 2 days now. I've added some extra parts into DSDT, tried different combinations in AppleHDA.kext and got some nice infos in both System Profiler and IORegExplorer.

Today I've updated to 10.5.7 and to my surprise I even got more interesting nodes in IORegExplorer (see screenshot attached). Looks like I'm getting close?

Anyway, I thought anyone might be interested...

Cheers,
mentorek

One more interesting screenshot... UPDATED



It seems I'm getting closer. Only few "Sound assertion..." errors. More info in System Profiler, updated info in ioreg.

Hi, Mentorek!

Nice news... But the other theme... I've flashed latest original BIOS 4.70. As I described earlier the screen and mouse is blinking every time. BUT!!! After I disabled one core of my Core Duo CPU in BIOS everything went normal Do You have any ideas how to fix this... I don't think that working with Core Solo is a good idea You see... I thought that there is a problem with my BIOS flashing. But... Now I think that there is something is my system... Maybe some driver needs to be installed or some driver needs to be removed I've tried 10.5.5 with Voodoo kernel and pathed ACPI and 10.5.6 with stock kernel and completely stock ACPI + Disabler.kext + Open Halt Restart.

With great respect, jazzminos.

[jazzminos]

I've noticed that SOMETIMES graphics get broken even with one core enabled

[jazzminos]

Hi! I've done DSDT patching with original BIOS 4.70. My graphics works perfect now!!! With stock kexts. And my network started to work. That was the great problem in 10.5.6. But still no sound... VoodooHDA causes kernel panic even if compiled by myself. Azalia gives no sound. Waiting for solution.

DSDT patching is absolutely amazing!

Thank you! I had no sound on my toshiba, after applying dsdt patch and modded Bios and was no sound yet, read your signature and decided to took out 1gb of ram, leaving just one (had 2x1gb) booted and sound works! Thanks! I was losing hope on my toshiba P100-103

Does anyone has bluetooth problems? Or anyone got the battery meter running? Tried all bundles and kexts and always shows no batteries available... Thanks!

[jazzminos]

Hi. I have Bluetooth problem too... It work only AFTER booting to Win... If I boot directly to Mac it doesn't work.

Battery meter work fine with one of the kexts (b15???)... I'm in Windows now. I can't upload it at the moment.

I have another great problem!!! NEED HELP!!! I have a terrible overheating in 10.5.7 and 10.5.6. It seems that fans don't work at all Any heavy CPU load leads to CPU temperature rise up to 83 degrees Then graphics falls... In Windows I have 54-55 degrees. Removing AppleACPITermal & AppleIntelCPUPowerManagement doesn't help. VoodooPower is installed and works, but no result. ik8fan is installed, but it seems that it doesn't work either Does anyone know what to do?

Thanks for reply.

Got similar problem with BT and CPU temperature.

I've tried to "enable" BT in DSDT somehow but I think there is some sort of firmware being loaded by Windows (or Linux) that is actually "enabling" it somehow.

As for battery meter I use VoodooBattery.kext

I have problems With VoodooPower though. After a certain time of inactivity it somehow results with Kernel Panic...

[jazzminos]

Overheating is the MAIN problem... I can't do practically anything. I can't even do a permissions repair... I've installed some old kexts from here - http://www.insanelymac.com/forum/index.php...st&id=43184 (http://www.insanelymac.com/forum/index.php?showtopic=101271&hl=CPU%20temperature&st=220) . And after that I failed to boot in normal boot I've tried to boot with -x and I had my fans working!!! But after that there was no success. Something prevents fans from working. This happens right after some kext gets loaded.

For me the kexts are actually working but I'm still using 4.20 BIOS or something...

Check out my DSDT.aml - maybe that would help you. It's not perfect but at least (partially?) working.

Hi, mentorek!

What kexts are working? That what I mentioned above? I can't boot with them... Maybe I need to do permissions repair... But I'll need to boot from DVD... With iATKOS 5i DVD all my fans work fine

I'll test Your DSDT override... And... Did You test Chameleon 2? Maybe I need to change the bootloader? I'm using EFI 9.

It seems that we need a completely new approach to ACPI... Maybe completely new drivers. Or we need a further development of VoodooPower to get fan control. Or maybe a special application like ik8fan, but with wider laptop support, not only Dell.

Maybe we need to write about this situation to Superhai... It is possible that he will take this problem into consideration during new version of VoodooPower development.

With great respect, jazzminos.

I'm using AppleACPI kexts and also VoodooBattery as VoodooPower results with Kernel Panics.

For me CPU fan is working - it even speeds up when CPU usage is going up.
I cannot find a way to test GPU fan... it's working during the boot, and I think it's blowing all the time but with a really low speed - I can barely feel it.

From what I've seen VoodooPower is just scaling the frequency and voltage of the CPU, I don't know (and I don't think) if it does touch fans at all.

Let's see what would change for you after DSDT.aml I've provided.
BTW. I'm using Chameleon 2 RC1 (build 438 or something). I don't know if there are any newer versions available.

[jazzminos]

Please, tell me from where can I download newest Chameleon and how to install it.
