Error Messages
Your application programs, operating system, and the computer itself can identify problems and alert you to them. When this occurs, a message
may appear on the computer's display or on an external monitor (if one is attached), or a flash code may be emitted.
If an error message appears on the display or external monitor, make a note of the message. For an explanation of the message and suggestions
for correcting any errors, see Table 1. The messages are listed alphabetically.

Message
Cause
Action
Auxiliary device
failure
The touch pad or external PS/2 mouse
may be faulty.
If you are using an external mouse only, check the connection for a
loose or improperly connected cable. If the problem persists,
enable the Pointing Device option. If the problem persists, call
Dell for technical assistance.
Bad command or file

microprocessor has failed.
Call Dell for technical assistance.
CD-ROM drive
controller failure 1
The CD-ROM drive does not respond to
commands from the computer.
Turn off the computer and detach the CD-ROM drive from the
media bay connector. Reboot the computer. Turn off the computer
again, reattach the CD-ROM drive to the computer, and verify the
media-bay cable connection to the back of the CD-ROM drive.
Reboot the computer. If the problem persists, run the CD-ROM
Drive tests in the Dell Diagnostics.
Data error
The diskette or hard-disk drive cannot
read the data.
Run the appropriate utility to check the file structure of the diskette
drive or hard-disk drive. See the documentation that came with
your operating system.
Decreasing available
memory
One or more memory modules may be
faulty or improperly seated.
Reseat the memory module in the upgrade socket. If the problem
persists, remove the memory module from the upgrade socket. If
the problem still persists, call Dell for technical assistance.

System Flash Codes
When errors that occur during the boot routine cannot be reported on the display or on an external monitor (if attached), the Num Lock, Caps Lock,
and Scroll Lock indicators (see Figure 1) may flash together in a pattern of lights (or flash code) that identifies the problem. For example, one
flash, followed by a second flash, and then a burst of three flashes (code 1-1-3) means that the computer was unable to read the data in nonvolatile
random-access memory (NVRAM). This information is important to the Dell support staff if you need to call for technical assistance.
The Num Lock, Caps Lock, and Scroll Lock indicators flash briefly when the computer is turned on. The flash codes, if needed, occur after the boot
routine.

No boot device
available
The computer cannot find the diskette or
hard-disk drive.
If the diskette drive is your boot device, make sure that there is a
bootable diskette in the drive. If the hard-disk drive is your boot
device, make sure that the drive is installed, properly seated, and
partitioned as a boot device.
No boot sector on
hard-disk drive
The operating system may be corrupted.
Reinstall your operating system. See the documentation that came
with your operating system.
No timer tick
interrupt
A chip on the system board may be
malfunctioning.
Run the System Set tests in the Dell Diagnostics.
Non-system disk or
disk error
The diskette in drive A or your hard-disk
drive does not have a bootable
operating system installed on it.
If you are trying to boot from the diskette, replace it with one that
has a bootable operating system.
Not a boot diskette
There is no operating system on the
diskette.
Boot the computer with a diskette that contains an operating
system.
Optional ROM bad
checksum
The optional ROM apparently failed.
Call Dell for technical assistance.
Sector not found
The operating system cannot locate a
sector on the diskette or hard-disk drive.
You probably have a bad sector or
corrupted FAT on the diskette or hard-
disk drive.
Run the appropriate utility to check the file structure on the diskette
or hard-disk drive. If a large number of sectors are defective, back
up the data (if possible), and then reformat the diskette or hard-
disk drive.
Seek error
The operating system cannot find a
specific track on the diskette or hard-
disk drive.
If the error is on the diskette drive, try another diskette in the drive.
Shutdown failure
A chip on the system board may be
malfunctioning.
Run the System Set tests in the Dell Diagnostics.
Time-of-day clock lost
power
Data stored in NVRAM has become
corrupted.
Connect your computer to an electrical outlet to charge the battery.
If the problem persists, try to restore the data. To restore the data,
press <Fn><F1> to enter the System Setup program. Then
immediately exit it. If the message reappears, call Dell for
technical assistance.
Time-of-day clock
stopped
The reserve battery that supports the
data stored in NVRAM may be dead.
Connect your computer to an electrical outlet to charge the battery.
If the problem persists, call Dell for technical assistance.
Time-of-day not set-
please run the System
Setup program
The time or date stored in the System
Setup program does not match the
system clock.
Correct the settings for the Date and Time options. (For
instructions, see "System Setup Program.")
Timer chip counter 2
failed
A chip on the system board may be
malfunctioning.
Run the System Set tests in the Dell Diagnostics.
Unexpected interrupt
in protected mode
The keyboard controller may be
malfunctioning, or an installed memory
module may be loose.
Run the System Memory tests and the Keyboard Controller
test in the Dell Diagnostics.
Warning: Battery is
critically low.
The battery is running out of charge.
Replace the battery, or connect the computer to an electrical
outlet. Otherwise, activate suspend-to-disk mode or turn off the
computer.
When the computer emits a flash code, write it down on a copy of the Diagnostics Checklist and then look up its cause and meaning in Table 2. If
you are unable to resolve the problem, use the Dell Diagnostics to identify a more serious cause. If you are still unable to resolve the problem, call
Dell for technical assistance.

Avoiding Interrupt Assignment Conflicts
Problems can arise if two devices attempt to use the same interrupt request (IRQ) line. To avoid this type of conflict, check the documentation for
the default IRQ line setting for each installed device. Then consult Table 3 to configure the device for one of the available IRQ lines.

Table 3. IRQ Line Assignments
Memory Allocations
Table 4 provides a map of the conventional memory area. When the microprocessor or a program addresses a location within the conventional
memory range, it is physically addressing a location in main memory.
Table 4. Conventional Memory Map
Table 5 provides a map of the upper memory area. Some of these addresses are dedicated to various system devices, such as the system/video
basic input/output system (BIOS). Others are available for use by expansion cards and/or an expanded memory manager (EMM).
When the microprocessor or a program addresses a location within the upper memory area, it is physically addressing a location within one of
these devices.

Table 6 provides a map of memory addresses reserved by the computer for peripheral input/output (I/O) devices. Use the information in Table 6 to
determine if the memory address of an external device (such as a PC Card) conflicts with a memory address reserved by the computer.
Check the documentation of the external I/O device to determine its memory address. If a device's memory address conflicts with a memory
address reserved by the computer, change the address of the device.
