__________________________________【 【 【 【 3】 】 】 】 DRAM Speed The DRAM timing is controlled by the DRAM timing Selection Registers. The timings programmed into this register are dependent on the system design. Slower rates may be required in certain system designs to support loose layouts or slower memory.
Page 24
【 【 【 【 3】 】 】 】 __________________________________ DRAM Data Select Parity, ECC, or Non-ECC, depending on the type Integrity Mode of DRAM installed in your system. The Choice: ECC, Non-ECC. CPU-To-PCI IDE Select Enabled to post write cycles from the CPU to the Posting PCI IDE interface.

【 【 【 【 3】 】 】 】 __________________________________ PCI and IDE Configuration 8 Bit I/O Recovery The recovery time is the length of time, measured in Time CPU clocks, which the system will delay after the completion of an input/output request. This delay takes place because the CPU is operating so much faster than the input/output bus that the CPU must be delayed to allow for the completion of the I/O.

__________________________________【 【 【 【 3】 】 】 】 Primary/ Secondary Each PCI peripheral connection is capable of activating up to four interrupts: INT# A, INT# B, INT# C and INT# D. By default, a PCI connection is assigned INT# A. Assigning INT# B has no meaning unless the peripheral device requires two interrupt services rather than just one.
【 【 【 【 3】 】 】 】 _________________________________ 3.6 Integrated Peripherals The Integrated Peripherals option changes the values of the Chipset registers. These registers control system options in the computer. Note: Change these settings only if you are familear with the Chipset. Run the Integrated Peripherals as follows.
