Removing A Card That Conflicts With The Card You Just Installed; System Board Options Screen; Isa Cycle Wait Control; Fail-Safe Timer Nmi - Dell 2200 User Manual

Removing a Card That Conflicts With
the Card You Just Installed
If there is a resource conflict between two ISA expansion
cards and you want to remove the card that conflicts with
the one you just installed, use the following procedure:
1. From the Steps in Configuring Your Computer
menu, select Step 2: Add or Remove Boards and
press <Enter>.
From the list of expansion slots and cards, select the
card in conflict with the one installed, and press
<Del>. When the utility asks you to confirm your
command, press <Enter>. Then press <Esc> to
return to the Steps in Configuring Your Computer
menu.
2. Select Step 5: Save and Exit, and press <Enter>.
3. Select Save the Configuration and Restart the
Computer, and press <Enter>.
The system reboots with the new system configura-
tion information.
4. If you deleted an expansion-card configuration file
from the previously saved system configuration
information, remove the card from your computer.
For instructions, see "Removing an Expansion Card"
in Chapter 7.
S
ystem Board Options Screen
The following categories appear on the EISA System
Board Options screen (see Figure 5-1) only if you press
<Ctrl><a> at the Welcome screen when you start the
EISA Configuration Utility:
•
8 Bit I/O ISA Cycle Wait Control
•
16 Bit I/O ISA Cycle Wait Control
•

Fail-Safe Timer NMI

•

Bus-Master Timeout NMI

•

Software Generated NMI

These advanced options are intended for users who are
technically knowledgeable. Do not change these options
from their defaults if you do not understand how such a
5-12 Dell PowerEdge 2200 Systems User's Guide
change will affect system performance. Some of these
categories may not apply to your system.
NOTE: To access the advanced options in modeling
mode, type sd /n /a at the operating system prompt and
press <Enter>. (To use modeling mode, you must run the
EISA Configuration Utility from your hard-disk drive.)

ISA Cycle Wait Control

The 8 Bit I/O ISA Cycle Wait Control and 16 Bit I/O ISA
Cycle Wait Control options set the minimum time
between back-to-back I/O cycles for 8-bit and 16-bit
ISA expansion cards, respectively. The default setting is
500 nanoseconds (ns).
Fail-Safe Timer NMI
When enabled, the Fail-Safe Timer NMI option allows
the generation of a fail-safe timer nonmaskable interrupt
(NMI). The default setting is Disabled.
Bus-Master Timeout NMI
When enabled, the Bus-Master Timeout NMI option
allows the generation of a bus-master time-out NMI. The
default setting is Disabled.
Software Generated NMI
When enabled, the Software Generated NMI option
allows the generation of a software NMI. The default set-
ting is Disabled.
M
odeling Mode
Modeling mode lets you create alternate .sci files to
accommodate different hardware configurations. For
example, if you regularly change the expansion cards or
their arrangement in your computer, you can create and
save a separate system configuration file for each configu-
ration and load that file after changing the cards rather than
having to create a new configuration file every time you
change your configuration.
NOTE: To use modeling mode, you must run the EISA
Configuration Utility from the hard-disk drive.
