Asus A7V SCSI slow!

Hi,

just installed a Asus A7V with Duron 800, and there are several questions/problems:
I have an Adaptec 2940UW, which serves the C: and D: disk as well as a CDROM and a CDRW drive.
On the ATA100 Primary Master there is one IDE Disk. There's also a Network controller, graphics is a Elsa Erazor III (which doesn't work correct yet, seems it gets no interupt).
When booting the PC (and also later) there are huge delays, i.e. nothing happens for ~5-10 mins. For example, after the logon, some icons are drawn on the desktop, the rest needs 5-10 mins. The PC seems to be frozen in these delays.
To me it looks like the access to the SCSI (C disk is blocked somehow.
Does anyone have an idea what that could be? I suspect, that it happened after the installation of the 4in1 drivers.

Other question: I did the voltage modification on the board to get higher core voltage for overclocking. The DIP switch has already been on the board.
When I set voltage to Auto, I get 1,99V which seems a bit high to me. When I select any other voltage, it seems like I can only get 2,05V no matter what setting I use. Since I only had a 22K resistor at hand, I used that one, expecting that the voltages would differ from the description on this site, but not that I only get ONE fixed voltage. Could the wrong resistor be the problem?
And: I've set the multiplier for the CPU to 10, should give me 1GHz CPU speed, but on boot it still says 800MHz. I connected the L1 pins on the Duron with a pencil, is that gone through heat? Or do I have to set anything else in the BIOS? Do I need to use jumperless mode?

Questions over questions, hope someone can help me here

I found that the problem of disk access disappears when i connect the IDE disk to the "standard" controller port. Though , still the graphics card behaves strange (I just get 16 bit colour, max 1024 resolution while possible should be 1600 at 32 bit). Weird all that is.
