Intel Desktop Board DX48BT2 Technical Product Specification 3.7 BIOS Recovery It is unlikely that anything will interrupt a BIOS update; however, if an interruption occurs, the BIOS could be damaged. Table 30 lists the drives and media types that can and cannot be used for BIOS recovery. The BIOS recovery media does not need to be made bootable. Table 30. Acceptable Drives/Media Types for BIOS Recovery Media Type Can be used for BIOS recovery? CD-ROM drive connected to the Parallel ATA interface Yes CD-ROM drive connected to the Serial ATA interface Yes USB removable drive (a USB Flash Drive, for example) Yes USB diskette drive (with a 1.44 MB diskette) No USB hard disk drive No Legacy diskette drive (with a 1.44 MB diskette) connected to the No legacy diskette drive interface For information about BIOS recovery Refer to http://www.intel.com/support/motherboards/desktop/sb/ cs-023360.htm 68
