If you are going to upgrade BIOS from BIOS version 1001.A (and earlier) for CUSL2, please make sure the following item in the BIOS setup menu is set at [PCI/AGP] before updating the BIOS with v1.27 flash tool.
In case the system is unable to start up properly after performing BIOS upgrade, please remove all the add-on VGA adapters from the system and start up the system with the onboard AGP graphics controller or clear CMOS. The add-on VGA adapters then can be installed after loading the setup default from the BIOS setup menu.
