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...PentiumGeek - Thursday, September 1, 2016 - link
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 :)Amadeus777999 - Wednesday, May 9, 2018 - link
Got an ASUS P2L97 board yesterday and I'm reading through this while DoomII is benchmarking. Good times.rogerjowett - Sunday, May 17, 2020 - link
Does n e 1 know where I can find a Voltage Regulation Module please
