Do not know about ACPI drivers, first i heard that they might be useful or even needed. The Win98 install was done with a different, much older board (and CPU), and it would be big time (a number of daze) to re-install as i would have to start from scratch: blank HD, install Win98SE with upteen programs, then Win2K and its umpteen programs, and try to get all the personal data (larger yet) across; ain't gonna happen. Device manager has two "motherboard resources" (really useful and helpful and complete info, eh?) as not satisfied, default works for monitor; am using a universal VBE9x driver for VESA mode 103 (600x800 256 colors) as the best found that actually works ("VBE MiniPort" by Anapa Corp). Does NOT work: UNIVBE.DRV - Win98SE continuously beeps at load and then freezes; muchly UNrecommended! My PCIE video board is the NVIDIA GeForce 8400GS; i have no clue as to the equivalent NVIDIA chip number on the motherboard. Sound does not work; the RealTek ALC662 chip drivers for older OSes are conspicusly absent (the ADS PTV-390 Conexant driver is also for "modern" OSes). Forgive me but i have really messy notes; things scratched out, notes added thenscrached, etc - BUT somewhere i got what seemed to be a proper driver for use in Win98SE; the Wdm_a406.exe which runs and *looks* like it installs. Other than that, it DOES NOTHING. Cannot say anything about the ethernet port; cannot test it as have no hardware for that. USB works except for a very wierd Verbatim "drive", the version i have was unique of 20 or so that are of identical type and name by them; used a universal "stack" program called "nusb32e.exe" which works like a charm. * Sorry about all of the info, but i think that others using Win98SE might want to know about possible options. ** Meanwhile, how do i get KernelEx to work? (and test it)
