While the operating system is loading, USB keyboards and mice are recognized and may be used to configure the operating system. (Keyboards and mice are not recognized during this period if Legacy USB support was set to Disabled in the BIOS Setup program.) 6.
Overview of BIOS Features 3.7 Boot Options In the BIOS Setup program, the user can choose to boot from a diskette drive, hard drives, CD-ROM, or the network. The default setting is for the diskette drive to be the first boot device, the hard drive second, and the ATAPI CD-ROM third. The fourth device is disabled. 3.7.1 CD-ROM Boot Booting from CD-ROM is supported in compliance to the El Torito bootable CD-ROM format specification.
Intel Desktop Board D915PCY/D915PCM Technical Product Specification 3.8 Fast Booting Systems with Intel® Rapid BIOS Boot These factors affect system boot speed: • Selecting and configuring peripherals properly • Using an optimized BIOS, such as the Intel® Rapid BIOS 3.8.1 Peripheral Selection and Configuration The following techniques help improve system boot speed: • Choose a hard drive with parameters such as “power-up to data ready” less than eight seconds, that minimize hard drive startup delays.
Overview of BIOS Features 3.9 BIOS Security Features The BIOS includes security features that restrict access to the BIOS Setup program and who can boot the computer. A supervisor password and a user password can be set for the BIOS Setup program and for booting the computer, with the following restrictions: • The supervisor password gives unrestricted access to view and change all the Setup options in the BIOS Setup program. This is the supervisor mode.

Intel Desktop Board D915PCY/D915PCM Technical Product Specification Table 48. BIOS Error Messages (continued) Error Message Explanation Update OK! NVRAM was invalid and has been updated. Updated Failed NVRAM was invalid but was unable to be updated. Keyboard Error Error in the keyboard connection. Make sure keyboard is connected properly. KB/Interface Error Keyboard interface test failed. Memory Size Decreased Memory size has decreased since the last boot.
Error Messages and Beep Codes 4.2 Port 80h POST Codes During the POST, the BIOS generates diagnostic progress codes (POST-codes) to I/O port 80h. If the POST fails, execution stops and the last POST code generated is left at port 80h. This code is useful for determining the point where an error occurred. Displaying the POST-codes requires a PCI bus add-in card, often called a POST card. The POST card can decode the port and display the contents on a medium such as a seven-segment display.
