5 Introduction Remarks on the Cyrix and IBM P200+ CPUs Please note that if you use a Cyrix or IBM P200+ CPU, you will have to set the frequency to 75MHz. You will also have to set JP16, the PCI bus frequency jumper to asynchronous to have the PCI bus run on 32MHz, in order to avoid problems with add-on cards. If you choose to run the PCI bus on a higher frequency, please use only high-end add-on cards that are specified to function on higher bus frequencies.
2 Hardware Setup This chapter is designed for Normal edition mainboard use only and it explains how to configure the mainboardÕs hardware. After you install the mainboard, you can set jumpers, install memory on the mainboard, and make case connections. Refer to this chapter whenever you upgrade or reconfigure your system. CAUTION: Turn off power to the mainboard, system chassis, and peripheral devices before performing any work on the mainboard or system.
