4-8.2 Assigning IRQs for PCI Expansion Cards
An IRQ number is automatically assigned to PCI expansion cards. In the PCI bus design, the BIOS
automatically assign an IRQ to a PCI slot that contains a card requiring an IRQ. To install a PCI card,
you need to set the INT (interrupt) assignment. Since all the PCI slots on this motherboard use INTA #,
set the jumpers on your PCI cards to INTA.
4-9 HTX PRO Technology
The IWILL
®
H4204 SERIES consists of several separate boards to form a complete 4-Way AMD
Opteron
TM
processor solution: Modularization of these three boards through IWILL’s HTX-Pro™
interfaces allows multiple possible configurations, each able to be optimized for size, thermal,
performance or other considerations. The I/O board is connected to the CPU board via a HTX-Pro™
interface. The data between Mainboard and I/O board transfer via the HTX Bridge. The HTX Pro is a
revolutionary design using the AMD64 Direct Connect Architecture to its full potential providing infinite
possibilities in customization and unparalleled bandwidth access in I/O intensive applications.
