Also gives the modules original header, where possible, to allow use of Phoenix tools later. So let's load that module to IDA Disassembler change extension if it complains and navigate to that position s. Preview of things to come: And that's the routines way of returning value.

It's the actual BIOS image. Use that as s4l00 when using disassemblers. The BIOS consists of many different modules, which are in last years also compressed. HDD checking functions are there. You have to guess, there are other cards, from other vendor IDs However, most things you might be after are located in Bios Code modules.

The easiest way now is to change the set carry instruction to clear carry. Strip the last zero, and you should get four-digit hex number. So you have individual modules. Security modules, and much more.

For WLAN, there's one more check - against second whitelist - which controls whether the card is connected to the leovo wireless switch - and if it does not pass there, it will get "radio disable" signal to pin Processor fan error messages are there actually directly, these are, to my surprise, not in Strings module.

The modules have byte header mentioned earlier, which mostly does not interest you, except four-byte integer at position 0xB. Get this number, it should end with zero in hex. This tool has been used to do all patched BIOSes currently available from me, since around summer bips, except for some rare cases when I had to do it manually because the patterns weren't found. Press C to tell IDA to try parse that wl400 to instructions.

Whitelist checking functions are there. You can modify it, yes, to include your card, but then you will have trouble putting the module back, because it might change size after compression - and it won't fit in place. There are Clear Carry and Set Carry - effectively set one bit in state register to zero clear or one set.

Modified may be even worse. Then let's find the beginning of the whitelist block. There are some option ROMs for all supported graphics integrated, discrete, all versionsfor ethernet card boot etc. With carry bit clear, there's either no card, or there's a supported card.

If you can't understand something, chances are you're lebovo with fire by not having enough knowledge. Also gives the modules original header, where possible, to allow use of Phoenix tools later.

You can mitigate that by changing also some other cards which you don't lenovk. Be aware it's big endian. So you need to modify one more check, and that one's a little more tough.

Not saying you're safe if you understood everything at once. Write that in the big endian way as two-byte integersand search lejovo 0x That is module location, and when there are far jumps or procedure calls, that is the address module will be referred with. Okay, so let's say we search the modules for something known To decompose the BIOS to individual modules for last generation, get phnxsplit written by me partially based on phnxdeco.

Easier than guessing the whitelist block beginning. Preview of things to come: And that's the routines way of returning value.
