intel board dx58so with post code 95

[FGABR5]

Boot stays for 4 - 5 minutes with a screen showing post code 95. After that the system starts normally.

Try a different keyboard.

95 is "Instructing keyboard controller to run Self Test (PS2 only)"

Also, what is your bios rev?

The latest bios for your board is 5600 from July 2013. I have attached it.

Install this bios and test the board/keyboard again.

Thanks. I´ll install it and give you a feedback about the results. I tried to boot using another usb keyboard but the problem was the same. I will apply the Bios update.

Is this Bios Update to be installed using F7 BOOT Option? If so, do you have the Windows EXE version? Fábio Cury Gabriel

[AlHill]

F7 is what you want.

Follow Scott's procedure to the letter.

5A is "Resetting PATA/SATA bus and all devices"

You could have a HDD or even a CD/DVD drive that is dragging down your system. Unplug ALL unnecessary drives and boot.

The problem was solved and as I could see, it was related to some kind of corruption or bug associated with SATA DRIVES CONFIGURATION. The Parameter HARD DISK PRE-DELAY was set to ZERO (0), the default value. I changed it to 5 (five seconds) and after that, the POST time was reduced to 7 seconds, including the 5s of the hard-disk pre-delay parameter. After that, I returned the parameter to the default value ZERO (no delay) and Windows boot time returned to normal (before the problem).

OBS: The problem started after a video card replacement (the old one was defective).

I´d like to thank you for all your support and help.

Fábio.

Glad you have it working.
