Hi; Changed over to a Ultra133 extra drive card from a ultra100.......much much better..all 4 drives on this card now working,and they are now there in windows.The question I have is on bootup,when first turned on when the promise card posts it dosen't always show all 4 drives there,unless I pause the computer before that for 10sec.or so,then the post shows all 4 drives.....either way they always are there after fully booted...Is this normal on startup??Maybe the drives need a few sec.to spin up?? I have a 550w power supply and using win xp pro....seem's to be ok after fully booted,maybe it just don't see it at post all the time,because it's so fast?
