e1000 card won't work in a PE2500, will in a 2600.

The hard specs for the system are:

Seven expansion slots - PCI slots are on three separate Peer buses
(64-bit/66Mhz, 64-bit/33Mhz, and 32bit/33Mhz buses) 
Two 64-bit/66Mhz PCI aka Green
Three 64bit/33MHz PCI 
Two 32bit/33MHz PCI slot (Slot 7 has the additional DRAC 2 connector)

Intel NIC
One open PCI busmaster slot, 32-bit or 64-bit, operating at 33 or 66 MHz 
One open PCI-X slot operating at 66, 100, or 133 MHz

The NIC card will work with 3.3v due to that being the new "better" spec for
hardware. You can tell the voltage looking at the slot key the 3.3v have a
plastic bar 1" from the end of the card, the end closest to the retaining
screw. The 5v is at the other end. On you NIC you will see two cut outs for
both plastic bars and this just means the card is universal. Going forward
3.3v will be the standard and 5v will start to go away (at least that's what
the hardware gods whisper in my ear ;-)).

This PDF will give you some idea of what I'm trying to say


I found it on google.com

Ahhh, thanks.  I only tried the other green slot.  The white ones are
64/33 5V according to dell.com.  I don't know how to tell 66MHz from
33MHz by eye.  If it works there I suppose the green PCI bus is

Is it safe to assume that because the bus in the 2600 where the card
is working is 66/64, the card must be okay at 66/64?  I can't tell
from the web site what voltage the 2600 signals at, but if it's 5V,
maybe the card doesn't like 3.3V signalling.

Yeah, another e1000 would be good.  Unfortunately the 2500 will be
serving files to a gazillion students for a few more weeks.  After
that I'll be able to do a proper James Herriot on it to find out
exactly what is wrong.

Thanks for your help.  With what you've said, after a few more
experiments I'll be able to be quite specific when I call the local
