UPDATE: George Breese, the resident VIA Chipset guru at VIA Hardware has this to say about the 4 in 1 silent patch: This patch detects the 0305, 3099, 3102, and 3112 (KT133x, KT266x, VT8662, and KLE133) *only*. On these chipsets, it will patch register 55 in the Northbridge, which will supposedly switch off a Memory Write Queue timer.
In the KT133A datasheet, register 55 is "reserved". But - yikes! - in the KT266, the documented MWQ register is register 95, not 55. Register 55 contains unrelated DDR timing adjustments and could actually be dangerous to program. For this reason, I do not recommend installing this driver on the KT266x chipsets until VIA examines this issue. For now, use WPCREDIT and set bits 5, 6, and 7 to zero in register 95 instead.

Looks like the next person to blame in this battle is none other that Microsoft. Makes sense to me. The problem alledgedly is not localized to VIA chipset motherboards, but also effects *ntel and ALi motherboards as well.
This driver is not just crushing Via or Intel systems but ALi systems as well. I am running a K6-III 400 MHz on an Asus P5A mainboard (ALi V chipset) using the latest BIOS, drivers and everything.
"However, upon installation of the 23.11 driver Windows 98SE is completely ruined and will no longer boot at all. At the point where the system should switch to the correct resolution the monitor will just display the background colour but no icons, mouse cursor or anything. Even trying to force VGA-mode from the boot menu will fail.
That is from a user at Icrontic (which I think is having network troubles). Actually, there is a small thread going in our forums about this. If everyone could share their experiences with this, maybe we can get to the bottom of this. That thread is right here

Note: As I posted in another thread - the "newer" (by three days) VIA 4.36a patches the patch that
didn't patch right.
