FT2200 (X1B) Motherboard (Rev 1.12.1)

RAM Configuration

The memory board comes already installed with the basic system. A total of eight memory banks composed of 16 72-pin SIMM sockets reside on the board. The sockets accept 8-MB, 16-MB, 32-MB, and 64-MB SIMMs for a maximum of 1 GB memory configuration.

Adhere to the following rules when you add system memory.

Always install SIMMs from bank 0. You should use the memory banks consecutively.

Always install SIMMs in pairs to fill up a bank. For example, for a total memory of 16MB, install two 8-MB SIMMs in a bank. You can not use a single 16-MB SIMM for a 16-MB configuration.

Use only fast-page mode parity SIMMs.

Install SIMMs of the same capacity in a configuration. For example, do not mix an 8-MB SIMM with a 16-MB SIMM.

Setting of jumpers J2, J3, J4, and J5 to set CPU1 VRM connector (J1) to 3.3V at 200 MHz.

Setting of jumpers J7, J8, J9, and J10 to set CPU2 VRM connector (J6) to 3.3V at 200 MHz.

SCSI Disk Array Backplane Board

The SCSI disk array backplane board provides a convenient interface between the SCSI drives and the system board. It includes eight SCSI drive slots to accommodate the drive trays, two SCSI channels to connect to the system board or SCSI controller board.

The backplane board has the following major features:

"Hot-swap" feature that allows replacement of a defective hard drive even while the system is in full operation. This feature requires a RAID controller board and RAID drivers.
Indicates hard disk drive failure through a front panel board LED
Supports wide SCSI or narrow SCSI devices
Supports mixed configuration of both fast-and-wide (16-bit) and fast-and-UltraWIDE (32-bit) SCSI drives in a single channel
Allows ‘split’ and ‘combine’ SCSI-channel configurations
SCSI ID strapping that allows wide SCSI HDD ID configuration through the backplane switches instead of configuring the individual drive IDs

Layout

Channel Configuration Switches

Jumper Settings

The backplane jumpers J3 and J4 allow you to select the terminator power source and set drive IDs. J3 supports the four upper drive slots (slots 1, 2, 3, and 4) on the backplane. J4 supports the four lower drive slots (slots 5, 6, 7, and 8). Default being setting 2 & 3.

SCSI Hard Disk ID Feature

You can avail of the ID setting feature by configuring the SCSI ID switches and jumpers J3 and J4 setting 3 on the bakplane board. Normally, you can assign seven IDs on the backplane (IDs 0 ~ 6). Closing the Setting 3 pins on jumpers J3 and J4 allow you to set eight additional SCSI drive IDs for the SCSI devices installed in the system.

Channel Configuration

Single-Channel Configuration

In a single-channel configuration, channel 1 supports the SCSI devices plugged into slots 1 to 8. Set the channel configuration switches to "Combine" and set the terminators accordingly to achieve a single-channel configuration.

RA1, RA2, RA3 RA4, RA5, RA6	Installed Removed

Dual-Channel Configuration

In a dual-channel configuration, channel 1 supports the devices in slots 1 to 4, and channel 2 supports the devices in slots 5 to 8. Set the channel configuration switches to "Split" and set the terminators accordingly to achieve a dual-channel configuration.

Additional Options

CMOS Setup

To enter the CMOS Setup screens press CTRL+ALT+ESC after boot-up.

There is no way of draining CMOS on this motherboard. There is an emergency boot procedure in the event of CMOS corruption. Hold down the F10 key and power on the machine, a single beep is produced at which time you may release F10.
