Motherboard Resources 2.6 PCI Interrupt Routing Map The PCI specification allows for sharing of interrupts between devices attached to the PCI bus. In most cases, the small amount of latency added by interrupt sharing does not affect the normal operation or throughput of the devices. However, in some special cases where maximum performance is needed from a device, you may want to ensure that it does not share an interrupt with other PCI devices.

AN430TX Motherboard Technical Product Specification Now, however, plug an add-in card that has one interrupt (group INTA) into the first PCI slot. Plug a second add-in card that has two interrupts (groups INTA and INTB) into the second PCI slot. INTA in the first slot is connected to signal PIRQA. INTA in the second slot is connected to signal PIRQB, and INTB is connected to signal PIRQC.
3.1.1 BIOS Flash Memory Organization The Intel PA28FB200BX 2 Mbit Flash component is organized as 256K x 8 (256 KB). The Flash device is divided into areas as described in Table 40. The table shows the addresses in the ROM image in normal mode (the addresses change in BIOS Recovery Mode).
For information about the version of PCI and Plug and Play supported by this BIOS, see Section 5.1. You can obtain copies of the specifications from the Intel World Wide Web site (see Section 5.2). Peer-to-peer hierarchical PCI Bridge is supported, and by using an OEM-supplied option ROM or TSR, a PCI-to-PCMCIA bridge capability is possible as well.
The BIOS support for DMI enables the maximum benefit from applications such as LANDesk Client Manager from Intel. The BIOS stores and can report on the following types of DMI information: BIOS data, such as the BIOS revision level Fixed information, such as data about the motherboard, peripherals, serial numbers and asset tags, etc.
Flash memory, so the BIOS can also report that information. Once this information is written, it is locked (read-only). Intel can provide a utility for making DMI calls to the BIOS. The latest DMI specification is available from Intel (see Section 5.2) and other sites.
E8000-E8FFF. You can use this area to display a custom OEM logo during POST, or can insert a binary image that executes at certain times during the POST. A utility is available from Intel to assist with installing a logo into Flash for display during POST.
To create a BIOS recovery diskette, you must make a bootable DOS diskette and place the recovery files on it. The recovery files are available from Intel. To recover the BIOS, turn off the computer and move the jumper to the BIOS recovery setting.
