BIOS ROM 8.5 Client Management Functions Table 8-3 provides a partial list of the client management BIOS functions supported by the systems covered in this guide. These functions, designed to support intelligent manageability applications, are Compaq-specific unless otherwise indicated. Table 8-3. Client Management Functions (INT15) AX Function Mode E800h Get system ID Real, 16-, & 32-bit Prot. E813h Get monitor data Real, 16-, & 32-bit Prot. E814h Get system revision Real, 16-, & 32-bit Prot. E816h Get temperature status Real, 16-, & 32-bit Prot. E817h Get drive attribute Real E818h Get drive off-line test Real E819h Get chassis serial number Real, 16-, & 32-bit Prot. E820h [1] Get system memory map Real E81Ah Write chassis serial number Real E81Bh Get hard drive threshold Real E81Eh Get hard drive ID Real E827h DIMM EEPROM Access Real, 16-, & 32-bit Prot. NOTE: [1] Industry standard function. All 32-bit protected-mode functions are accessed by using the industry-standard BIOS32 Service Directory. Using the service directory involves three steps: 1. Locating the service directory. 2. Using the service directory to obtain the entry point for the client management functions. 3. Calling the client management service to perform the desired function. The BIOS32 Service Directory is a 16-byte block that begins on a 16-byte boundary between the physical address range of 0E0000h-0FFFFFh. The following subsections provide a brief description of key Client Management functions. Technical Reference Guide www.hp.com 8-15
