BIOS/CMOS + POST

By

Art I've done in 2015 from my blog: blog.dd86k.space/post/pc-pixel…

Most modern computers use an EEPROM chip to store the BIOS. The list of the right is the Power-On Self-Test which goes:

  1. The CPU is powered on
  2. The CPU locates the BIOS
  3. The CPU tests various chips
  4. The CPU checks or sets the BIOS time
  5. The display is turned on
  6. RAM check
  7. Keyboard/Mouse check
  8. SATA check
  9. BIOS check (against older check or list)
  10. Plug-And-Play check
