Updating escd boot problem
All available options in BIOS are configurable via the BIOS Setup Utility.
If the POST test is cycled 1-5 times over and over either the jumper for this function is set to burn=in or the circuitry involved has failed BIOS checks for any extended information of the chipset and stores it in the extended RAM area.
It wasn't until the 1990s that the BIOS Setup Utility (also known as the BIOS Utility, or BCU) became common practice.
However, nowadays, BIOS has slowly been being replaced by UEFI (Unified Extensible Firmware Interface) in newer computers, which offers benefits like a better user interface and a built-in, pre-OS platform for accessing the web.
The BIOS Setup Utility is accessed in various ways depending on your computer or motherboard make and model. All modern computer motherboards contain BIOS software.
BIOS access and configuration on PC systems is independent of any operating system because the BIOS is part of the motherboard hardware.
The BIOS in some of the first IBM computers were not interactive like modern-day BIOSes but instead only served to display error messages or beeps codes.
