On a Compaq computer, how do I access BIOS Setup?

Note: If you need more Compaq-specific technical information and support, visit Compaq's support page at:

On a Compaq computer, you can usually run Setup by pressing a special function key or key combination during Power-On Self Test (POST), before the operating system loads. During POST, the BIOS usually displays a prompt such as:

Enter the designated keystroke to get into the BIOS Setup. Common keystrokes that will access the BIOS Setup are F1, F2, F10, and Del.

For older Compaq computers, like the Deskpro 286 or 386, you must place the Diagnostics diskette in the A: drive, and then restart the computer.

For newer Compaqs, like the Prolinea, Deskpro XL, or Presario, while the cursor is at the top right corner of the screen during bootup, press the F10 key.
