Does anyone care to explain to me about Via's drivers. I have Asus a7v333 and ata 133 hardrive and used the standard driver on my motherboard cd. Then i used the update 4.42 driver listed on this site. After applying service pack(i think)i am back to microsoft drivers and via's 4.38 or 4.41 or 4.42 install but dont show up in the device manager. I went to the Via Arena site and downloaded the 4.42 again and seen a note saying i should install the IDE miniport driver if i got (1)via chipset (2)ata133 hardrive. So i have both of the above so i download them i install 4.42,s still not showing up,i then install IDE miniport driver and on reboot i get a little window telling me some info so i select"dont show at next reboot" as it runs minimised at clock. I select the Via icon down at clock and a mebnu opens up letting me see detailed info on my master and prim and sec ide channels. It says my hardrive is set to udma mode 6 (ok fine) My cd/writer is set to udma 2 (ok fine) My dvd rom is et to udma 2(but lets me upgrade it to udma 4) I check device manager and all three ide parts are driven by Via but no info for prim and sec channel (ie driver numbers). I reboot and see my dvd rom is back to udma 2 (which i think it should be anyway. It wont let me install the Via 4 in 1 drivers unless i first unistall the Ide miniport driver. Im lost and what should i use or not use.
