why it is necessary to have Bios in a PC
He developed the CP/M operating system and also had a hand in the development of BIOS
Modern BIOSes will automatically probe the disk controller for information about the hard drive. It may still be necessary to enter the BIOS to set the correct boot order, however.
On power-up. You need to tap the escape key to stop the operating system loading, and enter the BIOS set-up screen.
The CP number is significant in this scenario because it helps identify the critical point at which a change in behavior or action is necessary for achieving a desired outcome.
You can find the necessary PS1 BIOS files on our website, along with step-by-step guides on how to install them properly for different emulators like ePSXe, RetroArch, and DuckStation.
You'll loose your BIOS settings and the computer won't be able to recognize some of the settings. If the battery goes dead, replace the battery, enter the BIOS settings and load the default, then do whatever is necessary under YOUR BIOS to recognize your hardware, then save the settings.

Upgrading the BIOS firmware is commonly referred to as "flashing the BIOS." This process involves replacing the existing BIOS software with a newer version to improve system stability, compatibility, or performance. It can also fix bugs or add support for new hardware. Proper caution is necessary during this process, as it can potentially render the motherboard unusable if not done correctly.
Its not strictly necessary on most modern computers, unless you have multiple hard drives on the system and want to ensure the proper boot order. Even then the BIOS is already aware of the drive; you're just telling it when to use it. In the ye olden days (say 1991), the BIOS wasn't able to autodetect the presence and configuration of the hard drive. It was necessary to manually enter the information so that the BIOS could load the operating system off the drive.
1. Enter BIOS, clicking Del on POST. 2. Enter Advanced BIOS Features. 3. Enter HDD S.M.A.R.T capability. 4. Click on disabled. Of course, different mother boards may have different functions organization; it is necessary to read the specific instructions manual.
Looking in the BIOS setup is often a necessary part of troubleshooting a computer, since the information in there can be wrong. For instance, if the system doesn't recognize a hard drive, then it is possible that it is not enabled in the CMOS settings. At other times, the CPU or the memory could be clocked too fast and leading to crashes and errors.
