Network card device name eIa, eWa, or eGa?

Hi,

What determines a network card's device name 2nd letter? eg what makes it a eI, eW, or eG device?

Is it machine dependend? eg if I have an EIA card in one machine, could it end up as EWA in another machine?

Does it relate to max speed?

Thnx,
Bob Kortlandt

SYS$SYSTEM:SYS$CONFIG.DAT

The device name is normally related to the
name of the device driver.

Not normally, no.

> Does it relate to max speed?

Not really. Note, for example, that an "EW"
could be a 10MHz-only Tulip chip/card, a
10/100MHz chip/card, or a Gigabit chip/card.

"What determines a network card's device name 2nd letter"

As with most devices, the second letter is a type (often using a single driver or driver family).

e.g. DK for SCSI disks, DQ for IDE disks.

I in this case means an Intel chipset.

Hi Steven,

The SYS$CONFIG.DAT gives me the answers I need, Thnx for the tip.

I will close the thread.

@all: Thnx for helping out.
