    • A system and method for storing adapter card Option ROM BIOS extensions on the system's DASD and, more particularly, on a partition of the DASD that is generally inaccessible to the operating system. The system may partition the system DASD into a user partition and a hidden partition where the hidden partition is preferably inaccessible to the operating system. BIOS extensions files are stored in the hidden partition. The system BIOS, when executed, identifies the peripheral devices on the system and interrogates the hidden partition for BIOS extension files corresponding to each of the identified devices. If the hidden partition contains a BIOS extension file corresponding to an identified peripheral device, the file is verified for authenticity. If the verification completes successfully, the BIOS extension file is copied into shadow RAM and control is passed to it. In one embodiment, each BIOS extension file are downloaded to the system's DASD using a standards-based update process that is independent of the vendor or adapter card type.
    • 用于在系统的DASD上存储适配器卡选项ROM BIOS扩展的系统和方法,更具体地,在通常对操作系统不可访问的DASD的分区上。 系统可以将系统DASD划分成用户分区和隐藏分区,其中隐藏分区优选地对于操作系统是不可访问的。 BIOS扩展文件存储在隐藏分区中。 系统BIOS在执行时识别系统上的外围设备,并询问与每个已识别设备相对应的BIOS扩展文件的隐藏分区。 如果隐藏的分区包含与识别的外围设备相对应的BIOS扩展文件,则验证该文件的真实性。 如果验证成功完成,BIOS扩展文件将被复制到影子RAM中,并将控制传递给它。 在一个实施例中,使用独立于供应商或适配卡类型的基于标准的更新过程将每个BIOS扩展文件下载到系统的DASD。
