How to extract fd. from exe. (Bios update)

[goodguy91]

Hi,
Im getting only 1/3th size picture in monitor from boot on acer travelmate 7520g. Bios shows travelmate 7720G bios 1.22 which is obviously wrong. I get full screen on external monitor.
Trying to flash 1.17v 7520g latest bios, but cant install windows and there is no fd. file so i could flash with ms dos or crisis mode ( FN + ESC at boot )

Three files are there flash.sys ABVXD.VXD and POM117.exe, tried already with few extractors with no luck.. dont have eeprom programmer yet so thats not an option to reflash chip.

Can anyone help me extract fd. file from this? I added the file on post.
thx

Try this, though its version 1.16
[If you don't have the battery connected, or low level, edit 'pom.bat' to skip 'ACERACDC.EXE']

I compared the POM116.rom file against POM117.EXE.

ISTM that the corresponding POM117.rom image can be extracted between 0xDA030 - 0x1DA02F.

I used HxD (a freeware hex editor) to do this.

exrtact the exe wih peazip

http://www.peazip.org/


btw, the exe is not the bin - forget your hex editor.
the exe is an archive containing the bin, a flasher, and some dll's all compressed.

The BIN is contained within the EXE in uncompressed form. The hex editor does just fine.

Re: How to extract fd. from exe. (Bios update)

couldnt extract it with peazip. trying 1.16 now but what value i should use for aceracdc?
if i remove whole line it gives me invalid directory when i try run phlas16 in dos. also tried value 0 ,didnt work.
there are no files over 8 digits, when i try run pom.bat straight it goes to bios update screen and red notice and beep `cannot read bios.wph´
I tried format my 4gb usb to fat and fat32

Re: How to extract fd. from exe. (Bios update)

Since bios says on system information acer travelmate 7720, wrong model. could that be the reason why it cant read bios.wph? tried renaming pom116.rom to bios.wph since it gives error `cant read bios.wph´ and it was stuck on recodnizing it.
when i removed aceracdc line completely from pom.bat it and run phflash16 it gives error
´invalid directory´
bad file name
´invalid directory

Re: How to extract fd. from exe. (Bios update)

Here is the section of POM.BAT that is causing your problems:

set UMAROM=POM116.wph

:NAPA
cd ATI
..\phlash16 /x /s /c /mode=3 /BBL %UMAROM%
goto end

Presumably your files are located in the flash drive's root directory. However, the BAT routine is looking for them in the ATI directory, hence the "invalid directory" message.

Your BIOS image is named POM116.rom but PHLASH16 is expecting POM116.wph.

Try typing the following line:

phlash16 /x /s /c /mode=3 /BBL POM116.rom

Re: How to extract fd. from exe. (Bios update)

Didnt rename any file and used HP USB disk storage format tool to create dos with 98boot files. Put all files pom.bat pom116.rom phlash16.exe aceraddc there,
removed whole aceracdc lines from pom.bat, used your new line:

..\phlash16 /x /s /c /mode=3 /BBL POM116.rom

I get now to phlash screen and step1 load image file = POM116.ROM, after 5mins it beeps error wrong signature error and asks for reboot

btw im usin 256mb usb stick.. so shouldnt be that big

EDIT: exact error msg is : platform signature not found in the interface

Re: How to extract fd. from exe. (Bios update)

ISTM that PHLASH is complaining that the BIOS image is incompatible with the target system.

You could try the command again with a few additional options. It still won't work, but the BU option should retrieve a backup of the existing ROM, and the DEV option should display the device information in your POM116.rom file.

phlash16 /x /s /c /mode=3 /BBL /BU=BIOSbak.rom /DEV POM116.rom

Re: How to extract fd. from exe. (Bios update)

Try the one attached:
1. Extract all files to the same location
2. Run the 'bat' file
(No need to rename or change anything)

[history:
1. Replaced 'phlash16.exe' with a recent one
2. Several changes to the 'bat' file
3. Invoked in force update mode
]

Re: How to extract fd. from exe. (Bios update)

Ok tried that command, thanks for this list also. It didnt save biosbak file on the usb with that command in pom.bat, same error. Or anything else.

Re: How to extract fd. from exe. (Bios update)

I have programmer now and it can read bios chip its mx25v8005,
found some acer travelmate 5220 bios files with same motherboard number but when i try try erase and overwrite it error always comes: The chips are not NULL!
both .bin file on chip and new file is around 1mbit. bios file im trying to flash also has 2nd file .rom file i cant use on software.

I already succesfully flashed another chip with this usb programmer so its working.

uploaded .bin which is on chip ( bad one ) and file im trying to overwrite it with.
anyone has working dump?
thx

techman you have full working dump for this one? thanks

If you can't erase the chip, then what difference will a "working dump" make?
