Page 11: Dynamic Branch Prediction
DYNAMIC BRANCH PREDICTION The Pentium processor uses dynamic branch prediction. To dynamically predict instruction branches, the processor uses two prefetch buffers. One buffer is used to prefetch code in a linear way, and one to prefetch code depending on the contents of the Branch Target Buffer (BTB). -
Page 12: Pci Chip Set
PCI CHIP SET The chip set consists of four devices: • The PCI, Cache, and Memory Controller (82437FX) • Two Data Path Units (82438FX) • The PCI/ISA bridge and IDE controller (82371FB) The 82437FX and 82438FX2 devices provide the core cache and memory system architecture, and the PCI interface. -

SUMMARY OF THE HP/PHOENIX BIOS This chapter is a summary of the main features of the new HP/Phoenix system BIOS. For a more detailed description, refer to the manual System BIOS for IBM PCs, Compatibles, and EISA Computers by Phoenix Technologies Ltd. Information for ordering this manual is given in the preface. -

C8000h to EFFFFh. BIOS I/O PORT MAP This section describes the HP BIOS port map. The next section provides more details about how the BIOS uses the system board components mentioned in the I/O port list. -
Page 23: Addressing System Board Components
ADDRESSING SYSTEM BOARD COMPONENTS This section provides more details of how the BIOS uses the system board components mentioned in the I/O port list. DMA Channel Controllers The system controller supports seven DMA channels, each with a page register used to extend the addressing range of the channel to 16 MB. - Page 24 Interrupt Controllers The system has two 8259A compatible interrupt controllers. They are arranged as a master interrupt controller and a slave that is cascaded through the master. The following table shows how the master and slave controllers are connected. The Interrupt Requests (IRQ) are numbered sequentially, starting with the master controller, and followed by the slave.

Page 25: Desktop Management Interface
DESKTOP MANAGEMENT INTERFACE This chapter describes an important feature of HP’s new style BIOS, the Desktop Management Interface or DMI. DMI INFORMATION STRUCTURE This BIOS presents a new method for storing and accessing information about the PC, called the Desktop Management Interface or DMI. -
Page 26: Accessing Bios Dmi Information
Overview of the DMI Information Structure ACCESSING BIOS DMI INFORMATION To access BIOS information, do the following steps: Locate the DMI header. Search for the “$DMI” signature in the segment E0000:0 or F0000:0. Verify the checksums. Refer to "Verifying the DMI Information Structure," in this chapter. Locate the first sub-structure table using the far pointer given in the DMI header. -
Page 27: The Dmi Header
Read off the required values. Each type of table has a pre-defined format. For a list of the major table types, refer to "DMI Sub-Structure Tables," in this chapter. Use the pointer to retrieve string values. All string values are terminated by a null (zero) value. THE DMI HEADER The DMI header is the starting point for all DMI information. -
Page 28: Dmi Sub-Structure Tables
DMI SUB-STRUCTURE TABLES Each type of table has a pre-defined format. Although the structure can evolve over time, new fields are always added to the end of the table and the length value reflects this new size. To parse several tables in order to find a specific table, simply use the table length. Using this method will ensure that the parser can function even when the tables evolve over time. - Page 29 PCMCIA device is present Bit 5=1 Infrared is present Bit 4=1 Two embedded serial ports present Bit 3=1 Mini-Tower (1) or Desktop (0) Bit 2=1 Embedded LAN present Bit 1=1 Using integrated video Bit 0=1 Supports HP LAN boot ROM...

Page 31: Power-On Self-Tests And Error Messages
The POST performs the tests in the order described in this chapter. The POST displays a graphic screen with the HP Vectra logo. If the POST detects an error, the error message is displayed. To see the tests performed during the POST, press [ESC] when the HP Vectra logo appears and the display will switch to text mode. - Page 32 Tests the level-two cache. A failure causes an error code to display and disables the external cache. Tests for the presence of HP SCSI ROMs. If SCSI ROMs are detected, their contents are copied into the shadow RAM area. A failure will cause an error code to display.
