How do I disable the on-board features?
On-board features can be disabled through the Server Board S845WD1-E BIOS Setup
program. Refer to the S845WD1-E Server Board Technical Product Specification.
Video:
What add-in AGP cards can be used?
The S845WD1-E AGP socket can accept universal AGP cards that comply with the AGP 2.0
specification. The S845WD1-E can use 1X / 2X / 4X card(s) operating at 1.5V.
Note: Legacy 3.3V AGP cards are not supported.
How do I designate an add-in PCI video adapter as my primary video adapter?
The primary video adapter can be changed from the onboard AGP to an add-in PCI adapter
through the BIOS Setup program. The setting is located in the Advanced screen under Video
Configuration.
Input/Output:
Does the S845WD1-E server board support Ultra ATA/100 hard drives?
Yes. The server board S845WD1-E supports Ultra ATA transfer rates up to 100 MB/sec
(ATA/100). An Ultra ATA/100 supported hard drive and an 80 conductor IDE cable are
required to take advantage of the increase bandwidth available on the IDE channel.
One of the new features of the Intel server board S845WD1-E is its ability to support all Ultra
ATA transfer rates (i.e., 33 MB/sec, 66 MB/sec and 100 MB/sec). To realize a true throughput
performance difference, a hard drive may need to implement higher spindle speeds, such as
7200 RPM, and a large onboard buffer size to take advantage of the increased bandwidth
available on the IDE channel.
Can I mix Ultra ATA devices with other devices on the same IDE channel?
If two drives with different Ultra DMA protocols are used on the same cable, the slower Ultra
DMA protocol is used for both drives. It is recommended that the Ultra ATA/100 drives be
attached to the primary IDE channel using the provided cable and that the other drives be
attached to the secondary channel using a good quality, 40-pin 40-conductor IDE cable, which
is not provided with the Server board.
Note: Some Ultra DMA cables use a hole in the ribbon cable as a cable detect mechanism to
determine if an Ultra DMA IDE or standard IDE cable is installed.
What type of battery is used in the S845WD1-E server board?
A 3 volt, (CR2032) coin cell is used to supply power to the Real Time Clock (RTC) when power
is not available from the power supply.
Why does my server board S845WD1-E system fail to boot?
The server board S845WD1-E has specific requirements for the power sequencing and limits.
A momentary switch should be used for the power on/off switch. The power supply chosen must
have the additional 4-pin +12 volt connector. If the power supply 2-by-2 (or 2-by-4) connector is
not plugged into the board connector located near the processor socket, the system will not
boot.
How do I disable the onboard LAN?
Onboard LAN can be disabled through the Server board BIOS Setup program. The setting is
located in the Advanced screen under Peripheral Configuration. Refer to the S845WD1-E
