*list at end of post* Hi, I started this list, as there is not much (modding) info on the MobilePRO BIOS out there. I really want to change the "Splashscreen" (IMAG001) and "Intel Logo" (OSBLOGO) on mine (Acer Aspire 9500). You will probably find RLE compressed graphics or PCX graphics if you manage to unpack the BIOS file, as I was able to find identical Insyde MobilePRO 4.20.10 BIOS files for different laptops, that can actually be decompressed/viewed with the InsyDeco tool and/or unpacked using 7ZIP (LZMA compression), to then view the "Splashscreen" using "Advanced Bios Logo Reader" or Photoshop, as it is PCX format. (all infos, tools and downloads in this thread) (My BIOS wont work, yet, as its probably a derivate of LZMA or changed file headers. I have also found similar ones like mine, with nearly identical file headers. (same compression ?) All MobilePRO 4.20.10. but also not editable. Its 512kb in size, but to "edit" it, it must be 1024kb (unpacked size) As said, it probably uses somekind of LZMA/LZH compression. The 1st tool that got my attention was : Insyde Decompressor from 2004 (original link dead, download available below screenshot) http://biosgfx.narod.ru/insydeco/ Download all Insyde Tools and Advanced Bios Logo Reader here : Compressed with winrar (4 megabyte). Everything is ready to use and doesnt require Easy 7 zip somthing anymore ;p http://www.file-upload.net/download-12183289/insydetools.rar.html Maybe we can put together a list of (all) old Insyde BIOS files here (Sony, hp, Acer etc.), from the years 2003 to 2006, so that I/us can find similarities between the ones that can and can not be decompressed using that tool and mabye find a way to uncompress the 512kb ones. Also Airis / MiTac laptops used at least "Insyde Software MoiblePRO 4.00.00". Maybe I can learn from those versions as well. Feel free to post. No H2O BIOS please. And I think we dont need to go back to 1996 Insyde Bios files either. Yakumo, Gericom etc. Thanks in advance. "Insydeco" is a DOS tool. DOSBOX works fine as well. It should look like this if you you type "insydeco "BIOS.ROM -l" InsydeBIOS information: Filelength : 80000 (524288 bytes) Filename : CL32103A.ROM BootBlock Table : 72800 Modules: : 22 Released : 16 January 2003 +------------------------------------------------------------------------------+ | Instance (Name) Packed Len CRC Segment Offset | +------------------------------------------------------------------------------+  BIGLOGO 0A2A C6F7 80000000 20400h  USBINT13 0EC5 61AB E0000000 20E40h  ACPIROM 08F1 6B0C E6000000 21D20h  ACPIDSDT 2443 B53C 40000000 22670h  BIOS SCU 3211 02E5 30000100 24AD0h  VGABIOS 9B1E 616A C0000000 27D00h  VGABIOS 251B 59A2 00000000 31840h  RSM_ENGL 2C2F 4F8F 63000000 33D70h  IMAG001 54F8 4BF6 40000000 369C0h  IMAG002 4BB6 D9F2 40000000 3BED0h  SCU SRVR 53B2 6D7B 70000000 40AA0h  PM PM 8005 65FA A0002C30 45E90h  PM PM 0AAB 9AED 00000000 4DED0h  PCI BIOS 259A 911A E7000000 4E990h  PNP BIOS 38A6 81A7 E7004000 50F60h  SYSBIOS A1F6 4B10 F0000000 54840h  SYSBIOS 29D1 E638 00000000 5EA90h  PXEBIOS 726B 28B6 D0000000 61480h  A7N8IIP 0DF3 5A08 90000000 68700h  A7N8PMP 0CC5 08F7 90000000 69510h  A7N8CMT 0F10 A45B 90000000 6A1F0h  CPOEM 094A 8E99 DA000000 7296Ch  ISC02 0235 0EB8 90000000 732D0h  ISC02P 0222 0035 90000000 73520h  CRISIS 1BBC 5BF6 80000000 7A430h As written in the beginning of this post, my BIOS is not getting recognized by this tool. Words like IMAG001 or LOGO are very common names for graphic files inside of these BIOS files, and it seems there are only certain parts compressed, as there is a lot of "clear text" inside the packed BIOS files.
