the monster has umm...
4 10mbps/scsi cards
2 fore 150mbps atm cards the rj45 ones
1 antares ultra wide scsi card
2 frame buffers...
1 soc (serial optical card)
I think the frame buffers are gx+ something or other.
Im going to take them out since I don't need them.
My plan with the atm cards was to hook my sparc20 and this monster
Together but I cant find the drivers for them for solaris 8, and
Openbsd 3.4 doesn't support this atm card :(
I believe the ultra wide scsi card is broken since It wont probe
Anything and just gives timeouts...
Here is a question... can I hook 2 atm cards together with just a

I played around with unplugging the fans just to see how they affect
The horrible horrible noise. The problem actually seems to be the
Front fan by the power supply. It is a small 13cm fan unlike the
2 20cm fans in the fan card. I cant honestly allow the power supply
to run without a fan on it but I believe I have a solution.
I am not an electronics type soldering person, but I believe I will
Get I think they are potentiometers which are little turn type knobby
Things that allow you to dial down how much voltage goes to something.
Three of those should do the job at turning the fans down so it can get
Enough cooling in it.
