While Intel was boasting support for EDO and PIO Mode 4 hard drives, VIA stole the limelight with support for not only EDO, but BEDO and SDRAM as well as UltraDMA hard drives over a year before Intel ever thought about supporting such options. The performance of the VP-1 today still isn't up to par with solutions from Intel and even more recent VIA contributions, however if you are looking for a low cost, feature rich chipset solution the Apollo VP-1 is the answer to your prayers.
It was this very design that inspired the design of the ever so popular VIA VP2 chipset as well as the VPX chipset which followed the release of the successful VP-1. Unfortunately VIA's VP-1 doesn't boast some of the Power Saving features found in the PC97 compliant VPX/97 and VP2/97 chipsets which makes it a viable competitor for Intel's 430FX and possibly even VX chipsets, however not for Intel's TX chipset which clearly holds the advantage is this case.

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
