BIOS Updates forum

Thanks for the tips. None of those worked unfortunately. On this model there is no jumper to clear cmos ram under the memory modules, and the C88 did not do the job. It seems after removing all the cables, and the small battery, it gets to POST (I haven't assembled it yet, just connected the displa...

I found an alternative method described for the A105 after posting my previous advice, so if that doesn't work, try this: 1) like always with anything that you do when taking your computer apart, take out the battery and unplug it (common sense) 2) Remove the plastic cover piece above the keyboard, ...

I Be wary of following the advice to blindly alter entries in NVRAM in a random search for the correct Token. Despite what that article says, it is possible to cause the PC to fail which could result in having to return it to the manufacturer. The reason I've gone to such lengths to determine a saf...

Well the answer is pretty clear when you know where to look! These PCs have a 32-bit northbridge (CPU <-> memory connector chipset) so can only address a maximum of 2^32 (4GB). Of that 4GB total the upper 1GB is assigned for PCI devices, graphics card memory, and other memory-mapped I/O devices. Acc...

First a related comment: My SZ is about the same vintage as your FE and also specs max ram at 2G. I just upgraded my wife's toshiba (AMD so her virtualization just works (drat)) with a 2G (Centon 2GB667LT available at some mass market outlets for $99) module. So I just thought I should try it in th...

If you had read this entire thread you'd know that the instructions on the Solaris forum you cite, and the examples it gives, were copied from this thread! Be wary of following the advice to blindly alter entries in NVRAM in a random search for the correct Token. Despite what that article says, it i...

Maybe it will be useful for anyone Sony vaio sz650n/c, bios version R0081S5 (0183) [0001] - enables AHCI (02EB) [0001] - enables VT-x Sony vaio sz650n/c, bios version R0101S5 (0189) [0001] - enables AHCI (02F1) [0001] - enables VT-x I wonder if the difference between AHCI and VT (0x168) can be tran...

To help hackers learn more about how it all hangs together I'm going to attach the contents of the Phoenix BIOS Editor's compilation log ( ROM.LOG ) for the BIOS related to the nvram.lst and nvtoken.lst reported here. I'm also linking to the raw files and in particular the 23,000-line bios.map that ...

Specifically, how did you obtain those nvtoken.lst and nvram.lst files? As I understand, those lst files are only for your FE but what about other people's models? No, the examples are not for the Vaio FE range. They are from a server motherboard based on an Intel 945GM chipset. As I said, some mot...

Here's an example of the NVRAM token symbols. In the following two comments I'm going to include the full text of the files mentioned here since they are so rare - hopefully search engines will index them and help others find this information. When compiling the Phoenix BIOS a couple of files are cr...

I have a Sony SZ370P with the same processor and same problem. (Rant: why they disable a key feature on a premium laptop I cannot understand. /Rant) I suspect it's to simplify their support options, since VT is variable across individual models (in the FE41 range, only the "Z" suffix has a CPU with...

So far, so good. I'm working with libx86 so the utility can run on 32- or 64-bit systems and make real-mode calls into the BIOS. It is the same library used by vbetool. libx86 combines Linux Real Mode Interface (LRMI) for x86 32-bit and x86emu for 64-bit. I'm fixing up some 64-bit bugs in libx86 rig...

I've been doing some scanning of /dev/mem with a userspace application with superuser privileges and made quite a bit of progress in finding the location of the Phoenix Dispatch Manager routine in a generic way. After opening /dev/mem as a file with open() I use the same technique that symcmos uses ...
