Which is better Bios Manufacturer? AMI Bios, Award Bios Or Phoenix

Basic Input/Output System (BIOS) also known as System BIOS, ROM BIOS or PC BIOS are the heart beat of the Computer Motheboard which the left of Cmos battery (Cr2032).



When Computer is on the sleep mode or unplug cmos battery is in charged on the bios clock to make it accurate and stock all the data of the computer when the last time operations, Main function of the Bios software is mainCore that all we need to make our computers Runs as we like,or things to connect to our computer like our Windows/Linux  or Mac OS. 
Here is the main purpose of a modern Bios 

• configure hardware
• set the system clock
• enable or disable system components
• select which devices are potential boot devices
• set various password prompts, such as a password for securing access to the BIOS user interface functions itself and preventing malicious users from booting the system from unauthorized peripheral devices

1. AMI bios or American Megatrends Incorporated (AMI) is an American hardware and software company that specializes in PC hardware and firmware. The company was founded in 1985 by Pat Sarma and S. Shankar, who was chairman and president as of 2011. It is headquartered in Building 200 at 5555 Oakbrook Parkway in Gwinnett County, Georgia, United States, near the city of Norcross.

• With a Dell computer, a 1-2 beep code can also indicate that a bootable add-in card is installed but no boot device is attached. For example, in you insert a Promise Ultra-66 card but do not connect a hard drive to it, you will get the beep code. I verified this with a SIIG (crap -- avoid like the plague) Ultra-66 card, and then confirmed the results with Dell. Submitted by John Palmer.

In These three giants of Bios makers which one is the Best.

As i Said before in my 10 years ++ experienced as a technician  i always  upset and disappointed of the perfornance of the AMI bios so my Heart goes to Award Bios 

Here are my Collection of my dead AMI bios Board 

i Can make a Vote poll For your Favorite Bios manufacturer
