Question about ASUS P4S533 Motherboard
After fail to bios update show "BISO Rom Checksum error"
SOURCE: can't boot bios
This is common after doing a BIOS upgrade. It usually means that the bios was successful, but that the motherboard is just now recognizing that it has a new bios. In other words, it's seeing that the new bios is not the same as the old one you had before, and is giving you a warning that it's changed. You can usually go into the bios, and clear all messages. This should make it go away.
Post your specific motherboard, and i'll see if I can get you more info.

Tips for a great answer:
You should make sure that all of the BIOS settings in the system are correct, by rebooting the system, going into BIOS setup and double-checking all the values hopefully against a recent
If you have reset the CMOS memory you need to go into the BIOS setup screen and reconfigure the BIOS. To do that you need to press a key while the computer is booting. Usually F2 but can be other keys. It should tell you on the bottom of the first screen which key to press to enter BIOS setup.
If you don't know the settings the should be one for optimal defaults - use that one. You will also need to reset the time and date.
Save, Exit and re-boot and everything should then work.
This error is not the same as a CMOS Checksum Error, which refers to corrupted values of the CMOS settings, the ones you set through the BIOS setup program. This error means the contents of the BIOS code itself are damaged.
During the boot process you will see on the screen a certain key to press to enter setup
Press and hold that key during the boot up process to enter BIOS you can load failsafe defaults or load optimized defaults ,press escape then press f10 to save to cmos to restart
You will also need to set the time and date
In the main or system setup screen you should be able to see the date and time Using your arrow keys navigate to the date and change the date. Once highlighted on the month, day, or year, press your arrow keys or your page up / page down keys to change the date.
hope this helps you
