This chapter is designed for explaining how to configure the HOT-597 hardware. After you install the
main board, you can set jumpers, install memory on the main board, and make case connectors. Refer to
this chapter whenever you upgrades or reconfigure your system.

HARDWARE INSTALLATION

Jumper Setting

This section describe the necessary procedures and proper jumper settings to configure the HOT-597
main board.

Jumper pin headers show on right side are used to
configure system clock, CPU multiplier voltages and
SDRAM clock speed.

System Clock and CPU Clock Multiplier - SW1

DIP siwtch finger 1 to finger 3 are used to adjust
System Clock from 66 to 100 MHz, finger 4 to finger 6
used to adjust CPU Clock Multiplier from 1.5x to 5.5x.

CPU Voltages - J19

Jumper group J19 are used to adjust onboard voltages
output from Switching regulators to CPU.

Futher more, HOT-597 Mainboard provide intelligent
CPU Voltages detecting and auto-adjusting function.
Enable this function by inserting a mini jumper pack on J19 row 2/3 (factory default), none of other mini
jumpers are required on jumper group J19. HOT-597 Mainboard will assign proper voltages to CPU
automatically.

SDRAM Clock Speed - Jumper JP9

HOT-597 support 100MHz external clock speed AMD 266MHz and 400MHz K6-2, and which allows
the user to use 66MHz normal SDRAM DIMM or 100MHz PC/100 SDRAM DIMM. Jumpers JP9 are
used to set SDRAM DIMM clock speed synchronous with System Clock (CPU External Clock) or
synchronous with AGP Clock.

Those hardware settings are made through the use of jumper caps to connect jumper pins on the main
board.

The following examples show the conventions used in this chapter.

Finger 3 set to ON,
the others set to OFF

Insert a jumper pack on J19
Row 2-3 to set CPU voltage
auto-detecting

Figure 2-1

Finger 4, 6 set to ON,

Memory Configuration

The HOT-597 mainboard provides three 168-pin DIMM sockets that make it possible to
install from 8MB up to 384MB of SDRAM. The DIMM socket support 8MB, 16MB, 32MB,
64MB, and 128MB 3.3V single- or double-side SDRAM DIMM.

The three DIMM sockets are arranged in four banks of one socket each, each bank provides a
64/72-bit wide data path.

HOT-597 provides optional data integrity features including EC (Eccor Checking) or ECC
(Error Checking and Correcting) in the memory array. EC mode provides single and multiple
bit error detection. In ECC mode, during reads from the DRAM, the HOT-597 provides error
checking and correction of the data.

To support ECC, you must use true (opposed to phantom parity generated by TTL chips) 72­bit parity-type DIMM for all modules.

Install memory in any or all of the banks in any combination as follows:
