Jetway S755MAX Rev: 1.0 BIOS Update

I am trying to update the BIOS on this motherboard, but it is telling me that it is write protected.
The manual states the option to disable this is in the BIOS settings in 'Miscellaneous Control' however, it does not appear in there.
I have been through the other BIOS Setup pages very carefully but cannot find any reference to it.
In fairness the manual contradicts itself as the picture of the 'Miscellaneous Control' page does not show the option! It shows what I can see.
When I try to update the BIOS it gets right to the end and says the BIOS is right protected, 'Check the jumper settings'.
So this indicates that the right protect is jumper controlled, however, I cannot find any jumper that seems to indicate in any way that it is for this.
I have also spent several hours Googling the problem with no results.
As this is Rev: 1.0 would this seem to indicate that this is an early version? The picture of the board on the Jetway website it very slightly different.
Anyway, can someone please help with this one because I really am tearing out my hair....what's left of it.
Many thanks

    Thank you for taking the time to respond.

    The Motherboard is a 'Jetway S755MAX' and on the board under the name it states 'Rev: 1.0.'

    If there is any further information required then please just let me know.

    Thanks again.

    Thanks for that.

    I do have a copy of this but dare I say the last section which details how to update the BIOS is incorrect (or appears incorrect) for my board. It states that you go to the 'Miscellaneous Control' section of the BIOS Setup and disable the 'Flash Part Write Protect'. Only problem is the option is not there!!! I have tried to do the update and it gets right to the end and states that the 'BIOS is write protect', 'Check Jumper Settings'. So this appears to conflict with the instructions.

    The version instaled is '755MAXA03.BIN' and I want to upgrade to '755MAXA04.BIN'

  • Sprocker Apr 29, 2008


    Thanks for your help.

    I am using the AWDFlash.exe for this, following the instructions in section 4-10 (page 43) but it just fails at the end saying BIOS write protect, check jumper settings.

    I am beginning to wonder if because this option is missing from the BIOS settings to disable the write-protect, does this effectively make it impossible to upgrade, as the option is actually part of the BIOS itself...if you see what I mean???

    Yes you are correct, the info on that page is incorrect. The new bios was put out in 05 and the manual you have was put out in 03. Hence why I do believe they are wanting you to use the Awdflash exe for the install... when you go to the main download page for the bios there is a link at the top regarding updating the bios...

    Here is a question, are you using the Awdflash.exe that they reccoment to use for doing the bios flash?

  • Kevin Flannagan
    Kevin Flannagan May 11, 2010

    After looking through the info on jetway website and going over the files for the bios updates, if you do not see the selection to disable the Write Protect in Miscellaneous Control of the BIOS then you have the latest version already. So, no need to update the bios.

    Hope this helps... if it dose let me know. Go to the following website... and the first to last listed is your Motherboard. (S755MAXR1A) open the zip file, it conatins a PDF file. Pay attent to Chaper 4 section 10. It will tell you just how to update your Bios.

    I am guessing that you already found the new bios that you are going to update to. Make sure you verify that it is the correct bios for *********** board and that it is an updated version. It looks to me like the bios for the mother board has not changed in about 4 years. But I could be wrong on that.

    What mother board are you updating the bios on? Make and model please... and yes it is going to be jumper controlled. I just need to know what mother board so I can tell you the correct jump.

I understand what you are saying. The only course of action I see left is to e mail the company and ask them if there is a way to skip the "disabling" step in the update. If there is no way to skip the step then I see no way to update the Bios.

Windows startup very slow win 7 sp1

this sounds like a BIOS update needed, I have a jetway motherboard that did the exact same thing and after visiting the manufacturers website and obtaining a BIOS Update my PC is now as fast booting up as it is when it fully loaded. Visit the dell website if you haven't already and go to the download and drivers section enter your service tag scroll down find the BIOS part in the drivers section, Then follow the on-screen prompts carefully read how to install it write it down if necessary then update your BIOS and within a very short time you should be booting up at light speed instead of turtle speed. Hope this helps.

Yes, it's the BIOS at fault here. Use an older processor (anyone as long it fits the socket will do) to run it for now. 
To update the BIOS you have 2 options: 1 - install completely (drivers, programs ,all) Windows, go to Dell and download (as in Save, not Run) the BIOS update utility (it's an exe) unto your pc, boot into Safe Mode and run it. This way has the advantage that is easy but you might stumble into problems with the WGA  - you might have to reactivate windows by phone.
2 - use the linux way -   For that you will need at least basic knowledge of command line operations - practically you will have to manually input 2 commands: one to goto the file ( cd place_of_file) the other to exectute it (run name_of_file). Best way if you know what you're doing it.

Athlon64 3200+ skt754.. Jetway S755max.. Dilemma?

$100 max.

This is okay for your basic internet usage. Sure, you can play some games on it but it's going to depend on the type / memory of the video card you put into it and the amount of system memory as well. With prices these days, I can sell you a dual core NEW computer for $399 and a quad core computer for $599 with specs that would blow that away.
