VL 5/XX MT SERIES 4 DESKTOP BACKPLANE VL 5/XX MT SERIES 4 MINI-TOWER BACKPLANE PROCESSOR The Pentium processor uses 64-bit architecture and is 100% compatible with Intel’s family of x86 processors. All application software written for Intel386 and Intel486 processors can run on the Pentium without modification. -
Page 12: Superscalar Architecture
SUPERSCALAR ARCHITECTURE The Pentium processor’s superscalar architecture has two instructions pipelines and a floating- point unit, each capable of independent operation. The two pipelines allow the Pentium to execute two integer instructions in parallel, in a single clock cycle. Using the pipelines halves the instruction execution time and almost doubles the performance of the processor, compared with an Intel486 microprocessor of the same frequency. -
Page 13: Data Integrity
DATA INTEGRITY The processor uses a number of techniques to maintain data integrity. It employs two methods of error detection: • Data Parity Checking This is supported on a byte-by-byte basis, generating parity bits for data addresses sent out of the microprocessor. These parity bits are not used by the external subsystems. •... -

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. -

Page 24: 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 25 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 26: 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 27: 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 28: 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 29: 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 30 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 32: 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 33 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.
