To configure the motherboard jumpers and set up the BIOS

Configuration 3—Series 757 motherboard, 300 MHz CPU, and 1.44 Mbyte floppy drive serial prefix range US3845 through US3909 with rear-panel label VIN # 0251 Infiniium oscilloscopes of configuration 3 were equipped with AMI Series 757 motherboards and the AMD K6/300 or K6-2/300 (300 MHz) processors. These K6 processors are dual- voltage processors with a 2.2 V core and 3.3 V I/O. These dual-voltage processors require a

2.2V voltage regulator module (VRM) in the motherboard’s VRM socket and that the J14 jumpers are set accordingly.

This motherboard lists the message "BIOS Release 757XXXXXX" and 64XXXKB of RAM when the BIOS setup is entered. See "To configure the AMI Series 757 WINBIOS Parameters with

1.44Mbyte floppy drive" for the appropriate BIOS setup procedure. See "Configuring the AMI Series 757 Motherboard for 300 MHz CPU" for motherboard jumper configuration details to match the K6/300 or K6-2/300 processor.

Configuration 4—Series 757 motherboard, 300 MHz CPU, and 120 Mbyte floppy drive serial prefix range US3919 through US3935 with rear-panel label VIN # 025 Infiniium oscilloscopes of this configuration were equipped with AMI Series 757 motherboards and the AMD K6/300 or K6-2/300 (300 MHz) processors. These K6 processors are dual voltage processors with a 2.2 V core and 3.3 V I/O. These dual voltage processors require a 2.2 V voltage regulator module (VRM) in the motherboard’s VRM socket and that the J14 jumpers are set accordingly.

This motherboard lists the message "BIOS Release 757XXXXXX" and 64XXXKB of RAM when the BIOS setup is entered. See "To configure the AMI Series 757 WINBIOS Parameters with 120 Mbyte floppy drive" for the appropriate BIOS setup procedure. See "Configuring the AMI Series

757Motherboard for 300 MHz CPU" for jumper configuration details to match the K6/300 or K6- 2/300 processor.

The respective motherboard jumper information and BIOS setups procedures are presented in the following pages.

Configuration 5—FIC Series VA-503A, 400 MHz CPU, and 120 MByte floppy drive serial prefix range US3949 and above with rear-panel label VIN # 03X2 Infiniium oscilloscopes of this configuration are equipped with the FIC Series VA-503A motherboard and the AMD K6-2/400 processor. These processors are dual-voltage processors with a 2.2 V core and 3.3 V I/O. The motherboard’s voltage select switch S1 must be configured for the correct processor core voltage.

This motherboard configuration lists the following message or similar at turn-on:

Award Modular BIOS v.4.51PG - An Energy Star Friend

Copyright © 1984-99 Award Software

Version JN4202

AMD K6T-2/X00 CPU Found

Memory Test: 65536K OK

See “To Configure the FIC Series VA-503A Motherboard BIOS Parameters” for the appropriate BIOS setup procedure.

(This configuration / vintage incorporates mechanical changes to the instrument chassis and cabling to match the change in form factor of this motherboard. See the Replaceable Parts chapter for new part numbers.)

2.Option 8ZE, remanufactured unit, may be older an configuration than the serial prefix number indicates. In this case, refer to the rear-panel VIN # label, floppy drive, and BIOS screen to determine motherboard configuration.
