4 BIOS overview This chapter describes the BIOS features of HP e-pc models.
4 BIOS overview BIOS summary BIOS summary The HP e-pc contain an HP/AMI BIOS. The system ROM contains the POST (power-on self-test) routines, and the BIOS: the System BIOS, video BIOS, and 3Com LAN option ROM. The system BIOS is identified by the version number IN.xx.yy. The latest BIOS version for your HP e-pc and instructions for updating the BIOS can be downloaded from the HP’s Support Web site at: www.hp.
4 BIOS overview BIOS summary • IDE HDD auto-detection, including support for IDE drives > 8.4GB • ATAPI CD-ROM auto-detection • PS/2 Mouse and Keyboard detection NOTE A USB floppy is installed as a standard drive by the BIOS (drive A: or E:). A USB floppy is installed as drive A: (for Windows 2000) or drive E: (Windows 98), depending on the number of external drives attached.
4 BIOS overview BIOS summary computer’s configuration. It can also be used to start the computer. • User Password. This password can only be set when a supervisor password has been set. The User Password prevents unauthorized use of the computer, protects stored data.
4 BIOS overview power saving and ergonometry power saving and ergonometry soft power down Soft Power Down is available with the Windows NT operating system. If users want to shut down their HP e-pc, they are able to do so directly from the Windows NT interface. There is no longer any need to physically switch off the HP e-pc. The hardware to do this is contained in the ICH chipset. This chipset is described in detail in Technical Reference Manual - HP PC Technology.
4 BIOS overview BIOS addresses BIOS addresses This section provides a summary of the main features of the HP system BIOS. This is software that provides an interface between the computer hardware and the operating system.
4 BIOS overview BIOS addresses Although the Setup program can be used to change some of the settings, the following address map is not completely BIOS dependent, but is determined partly by the operating system. Note that some of the I/O addresses are allocated dynamically.
4 BIOS overview BIOS addresses DMA channel controllers Only “I/O-to-memory” and “memory-to-I/O” transfers are allowed. “I/O-to-I/O” and “memory-to-memory” transfers are disallowed by the hardware configuration. The system controller supports seven DMA channels, each with a page register used to extend the addressing range of the channel to 16 MB. The following table summarizes how the DMA channels are allocated.
4 BIOS overview BIOS addresses IRQ (Interrupt Vector) Interrupt Request Description IRQ6 Free IRQ7 LPT1 IRQ8 RTC IRQ9 On board USB Controller IRQ10 VGA IRQ11 SCI ACPI IRQ12 Mouse IRQ13 Co-processor IRQ14 IDE Primary channel IRQ15 IDE Secondary channel.
4 BIOS overview order in which the POST tests are performed order in which the POST tests are performed Each time the system is powered on, or a reset is performed, the POST is executed. The POST process verifies the basic functionality of the system components and initializes certain system parameters. The POST starts by displaying a graphic screen of the Hewlett-Packard logo when the HP e-pc is started. Devices, such as memory and newly installed hard disk drives, are configured automatically.
4 BIOS overview order in which the POST tests are performed boot block recovery code check points E0 OnBoard Floppy Controller (if any) is initialzed. To start base 512K memory test. E1 To initialise interrupt vector table. E2 To initialise DMA and interrupt controllers. E6 To enable floppy and timer IRQ, enable internal cache. ED Initialize floppy drive. EE Start looking for a diskette in drive A: and read 1st sector of the diskette. EF Floppy read error. F0 Start searching 'AMIBOOT.
4 BIOS overview order in which the POST tests are performed 11 Going to check pressing of , key during power-on. 12 To init CMOS if "Init CMOS in every boot" is set or key is pressed. Going to disable DMA and Interrupt controllers. 13 Video display is disabled and port-B is initialized. Chipset init about to begin. 14 8254 timer test about to start. 19 About to start memory refresh test. 1A Memory Refresh line is toggling. Going to check 15us ON/OFF time.
4 BIOS overview order in which the POST tests are performed 43 To enable interrupts for diagnostics mode. 44 To initialize data to check memory wrap around at 0:0. 45 Data initialized. Going to check for memory wrap around at 0:0 and finding the total system memory size. 46 Memory wrap around test done. Memory size calculation over. About to go for writing patterns to test memory. 47 Pattern to be tested written in extended memory. Going to write patterns in base 640k memory.
4 BIOS overview order in which the POST tests are performed 80 Keyboard test started. clearing output buffer, checking for stuck key, to issue keyboard reset command. 81 Keyboard reset error/stuck key found. To issue keyboard controller interface test command. 82 Keyboard controller interface test over. To write command byte and init circular buffer. 83 Command byte written, Global data init done. To check for lock-key. 84 Lock-key checking over. To check for memory size mismatch with CMOS.
4 BIOS overview order in which the POST tests are performed A3 Soft error display complete. Going to set keyboard typematic rate. A4 Keyboard typematic rate set. To program memory wait states. A5 Going to enable parity/NMI. A7 NMI and parity enabled. Going to do any initialization required before giving control to optional ROM at E000. A8 Initialization before E000 ROM control over. E000 ROM to get control next. A9 Returned from E000 ROM control.
4 BIOS overview beep codes and error messages beep codes and error messages If a terminal error occurs during POST, the system issues a beep code before attempting to display the error in the upper left corner of the screen. Beep codes are useful for identifying the error when the system is unable to display the error message. Number of Beeps 44 Error Message Description 1 Refresh Failure The memory refresh circuitry on the motherboard is faulty.
