The system board in the server contains one 32-bit,
EISA/ISA-bus expansion slot and one 32-bit PCI-bus
expansion slot. The remaining slots are shared PCI/EISA
slots. The server supports only 5.0-volt adapters on the
PCI bus.
High-performance PCI adapters, such as RAID adapters,
are installed in the two PCI slots closest to the processor
board. See “Expansion Slots” on page 93 and “System
Board” on page 103.
Attention
To avoid possible damage to adapters and server
components, be sure the adapters do not touch each
other or the other components (such as the
microprocessor) inside the server.
Assigning Interrupt Levels:
A rotational interrupt technique is used to configure PCI
adapters. This technique enables the installation of PCI
adapters that currently do not support sharing of PCI
interrupts.
Always use the IBM PC Server EISA Configuration
Diskette for the system you are servicing when assigning
interrupts for EISA and ISA adapters. You cannot assign
an EISA or ISA adapter the same interrupt that you have
assigned to a PCI adapter. This is because the server
does not support interrupt sharing among PCI, EISA, and
ISA adapters.
If a situation occurs where you need an additional
interrupt, you can use an interrupt from another function
that you might not need, such as COM2 (Interrupt 3) or
parallel port (Interrupt 5 or 7).
EISA Configuration Diskette:
You must use the EISA Configuration Diskette anytime you
want to change resource allocations, such as:
Ÿ
Adding or removing devices
Ÿ
Moving devices
Ÿ
Changing device function
Ÿ
Resolving conflicts
Ÿ
Adding or removing EISA or ISA adapters
In addition, if you disable the serial, parallel, infrared, or
diskette drive in the Configuration/Setup utility programs,
you might need to run the EISA Configuration Diskette and
make the same change. Refer to the README file on the
EISA Configuration Diskette for more information.
Each time you use the EISA Configuration Diskette to
configure the server, the configuration information is saved
in a
System Configuration Information (SCI) file and in the
NVRAM configuration. Only devices that you install and
