BIOS Updates forum

Thx . I'm very happy to know it is working well.

Anyway, your "experiment" proves that the technique is usable even further. I've only experimented with one PCI card.

Thx for your info too

to all moderators, if you don't mind, please put the link to my Award BIOS Reverse Engineering Article in the collected wisdom. I don't mean to be famous because of this, I just think that there are lots of people want to read it and might need it. I remember the first time I do the BIOS reverse eng...

Perhaps someone want to read it :?: . Low Cost Embedded x86 Teaching Tool . It focused mainly on PCI expansion ROM. This article comes with sample source code. You need Linux and GNU Tools to compile the source code. In this article I prove that even a standard like PCI or PnP BIOS has a "flaw" that...

I've added routines to my BIOS (Award BIOS v4.51). Using a technique that I call "POST jump table hacking". For a couple of months it's stable enough, but recently I found that there still some minor issue. You might want to check it out : Award Bios "POST Jump Table" Hacking I don't know for sure i...

that's great .

@kodo :
Last time I asked Rainbow about this idea, this support is still under development. I don't know for sure if the current version already support it.

I think what you need here is an NT kernel mode driver to access the hardware. It's not that hard to make one an make works in win 2K/XP. I've made one it in the past to tweak my chipset's memory controller

I don't know for sure, but you'd better read the chipset datasheet and look for the registers in those chipset's related to the feature you need. Anyway, I think it's very possible that the feature you are requesting is hosted by a motherboard-dependent chip which is used for hardware monitoring. Pe...

also, PCI expansion ROMs, i.e. the one found in PCI expansion cards such as video cards were copied to RAM and executed from there (AFAIK begins at C000:0000h), since it's faster and is a requirement based on the PCI specification itself.

Realtek (RTL) based NIC can only be used for 1 Mbit chips since that's the biggest EEPROM chip capacity that RTL chip can decode, so, there is no workaround to make them supports chip with larger capacity.

I'm currently building a user mode application that need to know the "resource map" (i.e. the I/O map and memory map) of windows 2K/XP. I need to know how to obtain the I/O space or memory space that is consumed by PCI devices. This is needed since we can not invoke the BAR (base address register) s...

@ajzchips : I'm thinking about a "brute force" approach in this problem, in case we can't embed the new microcode to the BIOS itself. I'm thinking about this: find where the string ("Press F1...") lays in the BIOS binary then it must be a reference from somekind of call or jump instruction, then ju...

Hello everyone, I'm currently trying to edit my graphics card Device ID on a notebook using Phoenix BIOS v4.0 Revision 6. I have the modified Video BIOS prepared, checksum corrected, compressed, and inserted in the System BIOS. The BIOS is flashed, and when I check the Option ROM with PCI Scope, it...

in case my website is out of bandwidth, you can download the article at : The CodeBreakers Journal.

have a look at BorgNoOne BIOS tool collection here. I hope you found what you are looking for .
