FEATURES
BXB is based on the Dual Pentium
MHz (66MHz) or 300-450 MHz (100MHz) on Slot 1. The board is configured by an Easy-Setting-Single-Jumper (E.S.S.J.) to match your CPU clock speed.
®

2theMax designs all motherboards with the fewest jumpers to make your setup fast and
easy. The following will describe all of the jumpers that are required to be set before
moving on to step 2.

NOTE: Based on the implementation of the Intel 440BX AGPset the BXB is able to provide two front side bus (FSB) frequencies -- either 66MHz or 100MHz for Slot 1 processors and memory operations. The detect the correct FSB and set accordingly unless JP100 is set otherwise (see jumper JP100 below). The primary and secondary processor slots both operate synchronously at either 66MHz or 100MHz FSB, therefore if two processors are used both will need to be of the same type and speed; otherwise the lower of the two FSB frequencies will be set. When using the 100MHz FSB you must use PC100 compliant SDRAM.

Memory is an important component of any 100MHz motherboard. When selecting memory for use on your
2theMax brand motherboard we recommend using only the
finest quality modules. 2theMax would like to stress that using non-compliant PC100 SDRAM modules with a 100MHz FSB severely compromises the integrity of the system.

System Memory Configuration
Memory Layout
The BXB supports (4) 168-pin DIMMs (Dual In-line Memory Module). The DIMMs can be either EDO (Enhanced Data Out) or SDRAM (Synchronized DRAM). Do not mix EDO DIMM and SDRAM DIMM in the system.
SDRAM DIMM may be 100 MHz (10ns) or 125 MHz (8ns) bus speed.
SDRAM DIMM may be 8MB, 16MB, 32MB, 64MB, 128MB, or 256MB registered (see table 2).
100MHz FSB frequency requires PC100 compliant SDRAM memory.
4 clock SDRAM is recommended instead of 2 clock.
If using 50ns and 60ns EDO DIMM together you must set BIOS for 60ns.
Table 1 shows several possible memory configurations.
Table 2 shows compatible SDRAM components types according to Intel
440BX datasheets. (Internet: http://developer.intel.com)

Adaptec SCSI Setup
Introduction
InstallationBXB
The BXB
motherboard features the advanced Adaptec AIC-7890 Ultra-2 Wide
SCSI controller. This controller provides support for Low Voltage Differential (L VD) SCSI devices as defined under the Ultra-2 section of the SCSI-3 standard. L VD SCSI devices allow for data transfer rates of up to 80 Mbytes/sec and can use cable lengths of up to 12 meters! Additionally the AIC-3860 Adaptec control­ler is also provided for backwards compatibility with single-ended (SE) legacy SCSI devices such as SCSI-1, Fast, Fast Wide, Ultra and Ultra W ide.
Hardware Setup and Connector Descriptions
The motherboard can have attached a total of 15 SCSI devices. The 15 de­vices can be a combination of LVD Ultra-2 devices and/or SE Legacy devices but note that the SE Legacy controller can support up to 8 devices only!
Provided on the motherboard are three SCSI connectors. The first two being SCJ1 and SCJ2 are provided for single-ended (SE) legacy SCSI devices and will oper­ate at a data transfer rate of 40 Mbytes/sec (max.) using the 68-pin “Wide” connec­tor and 20 Mbytes/sec (max.) using the 50-pin “Narrow” connector. It is strongly recommended that all legacy SCSI devices be connected to either one of these two connectors. Due to the design characteristics of SE mode devices the cable length per connector should never exceed 3 meters with up to 4 SCSI devices and 1.5 meters with up to 8 SCSI devices.
External SCSI devices can be connected to the SCSI bus through the use of the included “external SCSI-2 port adapter.” To use external SCSI devices simply use onboard connector SCJ2 with an internal 50­pin SCSI cable. One end of the cable must attach to SCJ2 and the other end connects to the external port adapter. Internal SCSI devices can still be used, but just not on the ends of the cable.
Page 10
Installation BXB
The last connector labeled SCJ3 is a single 68-pin “Wide” connector for LVD mode SCSI devices operating at a maximum data transfer rate of 80 Mbytes/sec. The maximum cable length that can be used is 12 meters with up to 15 SCSI L VD devices. It is strongly recommended that no single-ended (SE) legacy SCSI devices be used on this connector as performance will drop to a 40 Mbytes/sec maximum with device and cable length limitations of the above first two connectors!
SCSI Bus Termination
Proper operation of the SCSI bus requires the following: each device must have a unique SCSI ID (including the SCSI controller) and the SCSI chain must have termination on each of the 3 onboard connectors. Termination is required at the last device on each SCSI cable.
T ermination for the majority of devices are accomplished by enabling a jumper or terminator resistor. No terminator is required for the SCSI controller onboard the motherboard as this will be set automatically. When using the “external SCSI-2 port adapter” the external SCSI device must provide termination.
The Ultra-2 (LVD) cable is provided with a terminator which attaches to the end of the cable.
