My desktop motherboard has a new BIOS released. Current one is E7786AMS v1.6; the new one is v1.7, which fixed some USB problem.
So as my habit, I like to keep things updated.
I downloaded the BIOS zip file from MSI official site for A55M-P33
Unzip it and put the files into a USB disk with FAT format.
Then, plugin the USB disk, restart the PC and hit DEL key to BIOS setting,click M-Flash, choose Select One File to Update BIOS.
It gave me the choice of USB disk and bios file.
It took less one minute to write to BIOS. When done, it auto-reboot.
Then I have the problem here. It can not load Windows 7 64bit. Even I tried to use the fix tool. Still not work.

Say, there is a ASUS Laptop, which is shipped with Windows Vista. Now the user want to change it to Windows 7. Here is the tips to upgrade it.
1) Backup up the user files to a safe place. Maybe USB disk or NAS.
2) Go to the official site of Asus, download the latest BIOS and upgrade it to the latest one.
3) Check the BIOS with the tool, Everest Ultimate, or any other tools you like, see if SLIC 2.1 included in the BIOS.
4) If there is SLIC 2.1 , it is ready to install Windows 7 without problem. Just download Windows 7 OEM iso and install it, fresh install or upgrade, both are fine.
5) if there is SLIC 2.0 only, there is something to do.

Sometimes I need to flash the mother-board BIOS from DOS. Actually now I have not tools can boot the PC to DOS. There is no floppy disk driver on it. I can only make a DOS bootable USB disk to do the job.
So I have the USB disk on hand. It is 2GB, the smallest capacity one I have.
The method to make a bootable USB disk is a little bit different from the one I blogged 6 years ago.
1) Download flash tools – HP USB Disk Storage Format Tool (Please google it and find the download link by yourself)
2) Download DOS package , named Win98 boot. (Also try to google it)
3) Decompress these two file.

What is UEFI, I mentioned it at What is GPT, but not clear. Here I would like to give more details about it.
The Unified Extensible Firmware Interface, UEFI, is a new firmware interface specification that is designed to replace the familiar BIOS interface.
When turn on the computer, UEFI’s firmware will run an inventory of the hardware installed on the system; after checking that everythinkg is functioning properly, it will launch the operation system and turn control of the PC hardware over to the software. UEFI supports a wider range of chip architectures, including 32-bit and 64-bit processors like the ARM chips, than does BIOS, which is limited to running on 16-bit processors.
The new spec works very well, and nearly all UEFI firmware images include support for older BIOS services, so it has no problem upgrading from a motherboard flashed with BIOS to one flashed with UEFI.
GPT stands for GUID Partition Table.
The widespread MBR partitioning scheme, dating from the early 1980s, imposed limitations which affect the use of modern hardware. Intel therefore developed a new partition-table format in the late 1990s as part of what eventually became UEFI. The GPT as of 2010 forms a subset of the UEFI specification.
To use GPT for partition, the system has to meet the following requirement.
New motherboard with UEFI support.
Linux has native support for it.
Windows 2008, Windows 7, only 64bit support it.

Acer Aspire One A110 has new bios released. I want to update it.
1) Download bios package from the official site.
2) I use the windows flash tool to update it.
3) Restart the netbook.
It is failed to boot up. When I press power button. It start to boot. I can go into CMOS setting by F2. But the fan is running so noise and after 10 to 20 seconds it power off automatically.
I can not even get into command promote.
I google it and find the solution.
