A4000 troubles.. Please help!

[stopthegop]

Hello,
Its been several years since I've actively used an Amiga. Through the latter half of the 1990s I was enlisted in the military and simply couldn't afford a really nice Amiga.   Thats past, and lately I gotten the "bug" to put together a nice A4000.  

Through various sources I've acquired the following:

-Working A4000D with Rev. B motherboard (battery removed).
-Working CyberstormPPC card 604e@233/68040@25.
-New Norway ethernet card
-New Indivision scandoubler
-OS 3.1 upgrade kit (disks and ROMs)
-OS 3.9 CD

I'm having two problems that may or may not be related:

1) The display quality is horrendous using the scandoubler.  Its barely visible and has that translucent "onion skin" effect.  Monitor is NEC 15" Multisync, which looks fine when hooked to a peecee.  

2.  I can't get the *^%$ IDE CDRom to work to save my life.  Its a standard 24x ATAPI drive, jumpered as a slave to the 2G hard drive, which is jumpered as master.  I've tried the other way around, but the machine won't bott at all in this case.  I have ASIMcdfs, but it locks up during install after I select to use the 'inquire' utility.  

Does anyone know how I can get OS3.9 installed in this situation and/or how to fix it so the CDRom is recognized?  Also, any ideas on the display problem?  Any and all help greatly appreciated!!  Thanks

Thanks.  Will try IDEfix and have another go.  I think the screen resolution is set to "NTSC Hi-res non interlaced"?  It doesn't seem to matter which one I select, they all appear as though the "brightness" control is turned all the way down (but its not, I checked).  Anyway, my hope is that by installing 3.9 the display problem will fix itself...  Wishful thinking, perhaps?

Thanks.  Have tried it with two CD drives, same results regardless of which one I use.  I'm thinking SCSI may be the way to go, but
1)I don't have a SCSI CDRom drive
2)I only have one scsi controller -the one on the accelerator- and that one I want to reserve for a nice fast Cheetah drive when I get it.  Won't having a slow scsi I CDRom drive bottleneck everything on the SCSI II bus of the cyberstorm?
