Chipset Guide

by Anand Lal Shimpi on August 1, 1997 9:36 PM EST
The market demanded for competitors to Intel's TX chipset, and until recently the only answer to those demands was VIA's VP2 chipset.   However, Silicon Integrated Systems, commonly known as SiS, released a successor to their popular 5571 chipset, the SiS 5597 chipset and a variant of it, the SiS 5598.  Those two single chip solutions are versatile enough to be used in virtually any form factor (LPX, NLX, AT, ATX) in a motherboard.   Although very little is known about the 5597/98 series, some of the features of the chipset include:

  • onboard VGA

  • UltraDMA support

  • SDRAM support

  • ACPI support

    The good ole' days when you could put multiple vendor CPUs into the same motherboard. So simple...

    This motherboard was on my 1st PC. I was very disappointed when faced with the problem that DIMM and SIMM memory can't work in the same time. I used Pentium 100Mhz CPU on this motherboard :)

    Got an ASUS P2L97 board yesterday and I'm reading through this while DoomII is benchmarking. Good times.
