To go to the various positions in given by ATOMBIOSReader in HxD I go to Edit -> Select block. It creates a text file of the same name as the file in the directory where the file is. I noticed that my R9 290's BIOS starts with 55 AA 44 and C92B1054 has that as well, so I deleted the data before it as seen here and saved it as C92B1054_cutdown.ROM. VBE7, Hawaii BIOS Reader, Tonga BIOS Reader, and Polaris BIOS Reader all did not read it successfully.ĪTOMBIOSReader fails to read C92B1054 as well. It is not a regular size, which annoyed many. Normally people have made BIOS Reader programs for the various GPUs, but none liked this C92B1054 file.
SLIC TOOLKIT GUIDE HOW TO
Figuring out how to read the C92B1054 file: Note that if using FPTw64's extracted dump it would end in _1607.Ĥ. On farther inspection of 365C62BA-05EF-4B2E-A7F7-92C1781AF4F9_1576.ROM it seems that it has all of the other smaller files within it. I searched using CTRL+F and searching ALL directions for the Text of BR23449.001 I did the work in the folder "including ATOMBIOS from Universal BIOS Backup ToolKit 2.0 rom" but it would be the same for FPTw64's extracted ATOMBIOS files, save for the file ending changing by 1 number. To identify the correct file, searching for the BIOS parameters found in the AMD Radeon Settings hardware tab in section 1. This means they might be the right file - just have to figure out which is used. The files have identical content, but their "Internal Number" that ends the extracted. ROM file of the BIOS.Įxtraction with Universal BIOS Backup ToolKit 2.0:Įxtracting with Universal BIOS Backup ToolKit 2.0 instead of FPTw64 and then doing the same Phoenix Tool and search steps yields basically the same files. FPTw64 can be gotten from here which I found on this forum. Now, for Phoenix Tool this site has it mirrored without making an account. This guide here shows how to get the BIOS and extract the BIOS into its pieces and search it for files that have the ATOMBIOS text in them.

Which means we need to extract the entire BIOS. Maybe something else depending on the russian guide (total commander)ĪTIFlash does not work on most laptop GPUs because the GPU's BIOS is embedded in the main system BIOS. Phoenix Tool 2.56 (latest I could find) at OR Universal BIOS Backup ToolKit 2.0 at google it, hosted on a couple of places Identifying info to find the specific 530 GPU used in the BIOS files. Min memory clock is 150 MHz (in line again) Min core clock is 300 MHz (in line again) Min voltage state is 800mV (in line with most of AMD's GPUs) rarĭellInc.-1.1.6.rom - the ROM file that * Universal BIOS Backup ToolKit 2.0 madeģrd Gen GCN Arch (R9 285 / R9 380/X area) aka Tonga-era But I'm hoping someone has had experience with something like this can help fix up its final flaws!įolder "DUMP files from FPTw64" - dump of the ROM that FPTw64 made (dumped using Phoenix Tools 2.50)įolder "DUMP files Universal BIOS Backup ToolKit 2.0" - dump of the ROM that Universal BIOS Backup ToolKit 2.0 made (dumped using Phoenix Tools 2.50)įolder "including ATOMBIOS" - has the files from the FPTw64 dump that have the word ATOMBIOS in themįolder "including ATOMBIOS from Universal BIOS Backup ToolKit 2.0 rom" - has the files from the Universal BIOS Backup ToolKit 2.0 dump that have the word ATOMBIOS in themĢ pictures that are linked in section 1.

ROM file - so it isn't able to be replaced.

Additionally, Phoenix Tool crashes when trying to replace the larger (you'll read below). Replacing the edited ROM causes the length of that BIOS' entry to change despite it being the same size. The issues I've run into are largely at the end, but any stage could use help as it's difficult at best. ROM file in BIOS with the edited version -> Write back to Laptop ROM file as desired -> Fix Checksum -> Rename ending to. The process used is: Extract BIOS from Laptop -> Dump BIOS -> Find relevant.
SLIC TOOLKIT GUIDE SOFTWARE
If successful should open the door for control over other mobile Radeon GPUs that don't play nice with OC software (low end stuff) - or even expand OC room for higher end stuff. The goal is to lower its power draw as it is too hot. The laptop in question is /u/cuongvfc 's and is a Dell laptop with an Insyde BIOS. It would be great if anyone has experience with this to let us know of better software/ways to get the job done better. This process involves a lot of steps and dated softwares.
