There is no way to "backup" the BIOS or to roll it back in case of a problem. Most problems occur when power is cut to the machine during the update. Just make sure the power doesn't go out or that the UPS is good, and if it seems to lock up, don't unplug it or power it off for at least an hour. Most times, the update will complete and just doesn't exit properly. Giving it an hour to complete is way more than it needs, but at least you won't be pulling the plug before the update is finished and ruin your motherboard.
As for the question of "should" you update it? Consider the updates to be applied and what additional functionality they offer or issues they fix, then weigh whether you feel you should:
A05: 1. Added a BIOS workaround for erroneous Linux boot Error Message ¡°invalid checksum¡± with certain system configurations. 2. Updated TCG ELog Checking. 3. Added a BIOS workaround to recognize certain QLogic cards. 4. Enhanced HDD check in PSA.
A04: 1. Added support for newer processors 2. Enhanced microcode selection algorithm 3. Corrected improper reporting of L3 cache size 4. Improved PCIE detection algorithm for x1 PCIE adapter
A03: 1. Improved OS licensing handling. 2. Fixed a potential power on issue with Remote Wake Up and ASF Mode enabled. 3. Fixed the ACPI table for Intel(R) VT for Direct I/O. 4. Improved the thermal solution for memory riser configuraion.
I have a T7400 running Windows 7 Utimate (64 bit) It started its life as a Vista (32 - bit I believe) . I upgraded to BIOS version A05, and have no plans to go to A06. Since A06 is optional I wouldn't bother with it. I have no idea what "inappropriate updates" are. I always accept all Microsoft critical and recommendated updates. Never been a problem.
Thank you both for your replies and the list of the actions is perfect. Just what I was wanting. :emotion-1:
MSGALE: On Vista 64-bit I had trouble with some of the updates it installed when on "automatically install" so I changed to "search but don't install" and looked to see if there were warnings in the event log. I sometimes got a message in the event log saying "this update is not suitable for your system". It usually came with another that was OK. After I discovered this I would deselect these and keep the others. Unfortunately the system was compromised before then. I am hoping I will not have this trouble in Windows 7.
