Table 1-1. Installation Troubleshooting
Problem Solution
The board’s power LED does not
light when the power supply is
turned on.
The black MicroPower Off button, SW5,
needs to be pressed after power-up.
The board’s power LED does not
lightevenaftertheMicroPowerOff
button, SW5 is pressed.
Check power supply connections at P25
and P26.
The red power LED is on but I see
nothing on the VGA monitor and
do not hear any beeps from the
speaker nor hear the head
synchronization on the disk drive.
Ensure processor reset by pressing the red
Reset button, SW2.
I hear a beep on the speaker butsee
nothing on the VGA monitor. Check that the monitor has AC power. Check that the monitor is correctly
connected to the VGA display adapter.
Check that the display adapter is correctly
seated in the ISA slot.
I get the startup message on the
monitor but it says there’saCMOS
checksum error and doesn’t finish
booting.
This is the normal condition after power-
up. The ÉlanSC310 microcontroller
evaluation board’s CMOS RAM does not
have battery backup. Follow the BIOS’
instructions to run the Setup utility to
configure the CMOS RAM. Once
configured,theCMOSRAMcanbesaved
by leaving the power supply on but using
the MicroPower Off button, SW5, to
power down the board.
I’ve configured the CMOS RAM
butI don’thear any soundfromthe
disk drive and the system does not
boot from the diskette.
Check that the 34-wire cable to the disk
drive is properly connected at both the
disk-drive end and the board end (board
connector P27). Check that the CMOS
setup indicates that drive A is a 3.5"
1.44 Mbyte drive.
I hear the diskette being accessed
but get an error message "Non
System disk".
Check that the diskette in the drive is
indeed bootable, just as you would on a
standard PC.

Connecting an IDE Hard Drive
This section describes how to connect an IDE hard drive to the ÉlanSC310
microcontroller evaluation board. You need to provide the following additional
items:
• An IDE-compatible hard drive of size not more than 512 Mbyte. See the
appendix “Verified Peripherals” on page B-1 for a list of hard drives that are
known to work. Note that Connor and Fujitsu hard drives do not work with the
ÉlanSC310 microcontroller evaluation board.
• A standard 40-wire AT IDE cable.
Assuming you have successfully booted to DOS from a disk drive as described in
“Booting DOS From a Diskette” on page 1-2, do the following:
1. Disconnect power by unplugging the PC power supply from the AC outlet.
WARNING: If the PC power supply is on but the board
hasbeenputin astandbymode usingtheMicroPowerOff
button,thereisstillsomepowerontheboard.Completely
unplug the power supply before continuing.
2. Inspect the 40-wire IDE cable that you are providing. The red wire along one
edge of the ribbon cable indicates wire 1. Connect one end of the 40-wire IDE
cable to the hard drive just as you would for a standard PC installation. The
hard drive documentation should indicate where to put wire 1. Connect the
other end of the 40-wire IDE cable to the 40-pin connector P28 on the
ÉlanSC310 microcontroller evaluation board with wire 1 toward the ROM
sockets.
I get a "Missing Keyboard" error
message on the monitor during
boot-up.
Check that keyboard is properly
connected.
There is a problem you cannot
resolve. Contact the AMD Technical Support Hotline at 1-800-222-9323.

3. Find one of the 4-wire powerconnectorsfrom the PC power supply andattach
it to the 4-pin connector on the hard drive just as you would for a standard PC
installation. The hard drive documentation should indicate the proper
orientation of the power cable.
4. ApplypowertotheÉlanSC310microcontrollerevaluationboardbyconnecting
the PC power supply to an electrical outlet. Then press the black MicroPower
Off button, SW5. The red LED should now be lit.
5. Press the red Reset button, SW2. You should see the BIOS boot message on
themonitor.Whenbootingafterapower-up,theCMOSROMisnotconfigured
and you need to use the BIOS setup utility. Follow the instructions shown on
the monitor to enter the Setup utility.
6. In the BIOS setup utility, you need to configure Drive C for the proper number
of heads, cylinders and sectors. (Some BIOS products have an AutoDetect
feature that automatically detects this information; some require you enter this
information manually.) You should be able to get these numbers from your
hard drive documentation. Follow the prompts to save this configuration and
exit the BIOS setup utility.
7. Whether or not your hard drive contains an already installed bootable disk
image (written from some other PC), you should still keep your bootable
diskettein the A drive and boot from that. After you boot properly from A, try
to do a directory listing of C. If the directory listing of C works, you can try
removing the diskette from A and booting from C (Ctrl-Alt-Delete). Note that
not all BIOS’ have the same mapping of logical to physical sectors on a hard
drive, so if your hard drive was written by the BIOS on some other computer,
it may not be readable by the BIOS on the ÉlanSC310 microcontroller
evaluation board. If you are unable to boot from C, you should reformat the
harddriveforuseontheÉlanSC310microcontrollerevaluationboard(seeyour
DOS documentation for how to reformat your hard drive).
