i have two problems, wich i don't know if are related so sorry in advance for the long posting..

MY CONFIGURATION
asus p4b266-c
intel 1,6
pulsar 2 3.1
512 ddr
2 hd maxtor
3 com lan
matrox 450 dh
running on xp pro, standard mode.
daw assembler, when installing, to save mobo resources disabled audio onboard in the bios (there are two items related: onboard pci audio and onb. ac97 audio controller).
audio playback in nuendo and other stuff going well, but i had no midi in available in dev setup (in nuendo and cubase), no playback in wave lab, audio cd's and other appl like wmedia player.
in "sounds, etc." icon in c. panel tabs were grayed out (no audio playback, no midi etc,). in the hardware tab creamware was audio -midi enabled
these problems happened with every kind of sfp project... i tried for weeks..
then i enabled the 2 bios audio option (because i can't decide wich one to choose..) and loaded asus audio driver.
playback wavelab, mediaplayer, midi in to sequencers ok for two fantastic hours. "sound icon" showed in playback tab audio and midi activated

boot again and et voilà greyed sound tab, with all the above mentioned problems (still there was in "hardware tab " the c audio driver apparently working..)
and then, the second strange vehaviour: i opened a project and suddenly a "copy protection" violation error, then "pci master- abort, check for pci board conflicts and restart the computer". all this with projects that BEFORE enabling onboard audio were going ok..

a third message appear now : "pci master overflow" ..with only few audio samples to reproduce..
in the end pulsar simply do not opens ANYMORE:"hardware version 30 detected. you need a software update",
or "hardware cannot be setup properly- installation error: pulsar2 sramtest failed:
data 0x40000000 reads 0x00000000- please chek hardware conflicts".
adresses for cw is - slot pci 3 (bus pci 2, peripheral 11 ,irq 09
for c driver- bus pci 2, peripheral 11, irq 07
no conflicts are mentioned in hardware -peripherals.
in the bios pci configuration is set to auto for all slots requiring an irq
acpi suspend to ram disabled
in boot menu plug and play o/s is set to NO.
i don't have the experience to understand if the audio- midi problems and the copy protection + installion error, etc are related.
i know several persons in planet Z had problems with copy protection error anyway. it seems in theory better DISABLE audio on board, but how to manage the thing in the way playback and midi in work properly? could all this involve acpi mode? or maybe it's the classical obvious solution i actually can't see..
i will try to reinstall pulsar, flash bios, and stuff like that, but in the meanwhile every enlightenment is precious
