Acer Aspire 9500 - Insyde ACPI Bios 4.20.09 from 2005

[Boost]

Hi, this is not a double post, as Im also in the "Insyde BIOS unlock request". Here I just wish for the Splashscreen to be changed.


I stumbled across this tutorial by donovan 6000 :

Changing Splashscreen

But still, even Andys Tool says "no Insyde Bios".

The original downloadable BIOS v1.70 that I flashed back then looks like this :



Here is the link to the BIOS :

Acer Aspire 9500 (Modell DQ70).

Mainboard: Compal Stork (Chipset i915PM/GM, Southbridge 82801FBM (ICH6-M)

Pentium M 760 @ 2 GHz

Insyde Software MobilePRO Version 4.20.10, using the "Acer HQD70" Bios 1.60. (512kb)

Right after startup it additionally says "Insyde ACPI Bios 4.20.09" short before initialising the HDD and the CD-Rom.

I made a backup of the 1.60 using the "Universal BIOS Backup ToolKit 2.0" but couldnt open it either.

Its UUID is : 61373537326131356136000FB0F07732

Firmware 101.114
Bios Date: 12/29/2005
Bios Starting Segment : EB00h


I gave up and I really hope someone else found a way in the meantime, as I just digged out this laptop once again.

And reply is welcome.

Regards,
Boost

There is a tool (InsyDeco), a decompressor, from 2004 that lets you decompress Insyde BIOS .

And there is the "Advanced BIOS Logo Reader" :

"InsyDeco" can be downloaded here :
(I could only unpack it with "Easy 7 Zip". "Winrar" and "7-Zip" failed!)

The "Advanced BIOS Logo Reader" can still be downloaded here :

Also found the very 1st BIOS for it, v1.30 from 2005 :

Its not working with my Insyde BIOS, so good luck to everyone else from 2004.

I found similar BIOS files from other manufacturers and the ylook nearly exactly the same.

The ROM itself probably uses some LZMA/LZH LZ77 derivative and the decompression routine can be found
in one flashit.exe of a Fujitsu Amilo L7310W (r1.08), but has yet to be examined.

A Toshiba A105-S361 (v2.00) uses the same BIOS version, but it is not encrypted and can be editet with the desired tools.

Graphics are usually called IMAG001, BIGLOGO and/or OSBLOGO in these kind of BIOS files
and are 8-Bit RLE compressed PCX images that can be viewed and edited with Photoshop.
