Apple-branded "Fast Ethernet 10/100BaseT card" (PCI) "SA0025"

Does anyone know which Apple driver/extension this card uses? The SA0025 is apparently just a re-badged ZNYX NETBLASTER ZX345. Both boards are silk-screned with "SA0025" on the PCB, and appear identical, besides the sticker on the 21140 chip itself.

For the record, the Apple 10/100 PCI card is actually just a DEC 21140-based Ethernet card:

The following is taken verbatim from a 1998 Apple document, labeled "033-1014-A",

Update: About the Optional 10/100Base-T Ethernet Card

Some Macintosh computers come with an optional 10/100 Base-T Ethernet card installed. This
update provides details about the card that are not covered in the computer’s manual.

I AltaVistaed the card, and it apparently uses the "Apple Enet" extension ... but it has to be the correct Apple Enet extension from the Beige G3 or later. I suspect so long as it is installed while you install the OS, anything OS 8 or later will likely install the correct driver for the card.

I can confirm that the "Apple Enet" extension, version 2.4.2, works properly with this Apple-branded card, which is actually a re-badged ZNYX NetBlaster ZX345. I've attached a self-extracting, macbinary-encoded archive, containing just the necessary Extension, to this post.

According to a nearly 21-year-old MacInTouch post, version 2.4.1 of this extension had a memory leak. The Apple ENET Extension version 2.3 may also work with this card, but I haven't yet validated it.

Apple Enet extension version 2.4.2 originally was distributed as part of an image, published on Apple's FTP site, Apple_Ethernet_Update_2.0.smi.bin

I recently received the same Apple-branded card and when installed in my beige G3 running 9.2.1 with the 2.4.2 Enet extension, the machine will not boot past the happy mac screen.

I reset the PRAM but still no boot. I have yet to move the card around to different PCI slots but before I do, does a no-boot situation like that lend itself to a problem with the card itself?

if I could be permitted to hijack this thread a bit - has anyone on here gotten this card working on a 6400/6500/Tam? I still haven’t been able to get Ethernet on my 6500 (see previous post here). The card discussed here is for sale on eBay for $30.

one main problem unrelated to the card, Ethernet is missing from my system under tcpip. Ppp and AppleTalk are my only options & I don’t know why. I loaded the os with the Ethernet card installed But maybe because the card isn’t liked by my system it didn’t trigger the needed code to be installed when I installed the OS?

Any help here would be much appreciated.

It most likely didnt install the extensions because it wasnt present when you installed the OS.

I think a program called TomeViewer is used to extract them from the installer.

Yep. Same with the DVD Player app, etc. Only installs support for what's physically present when the installer is run, unless you choose a custom install at that time.

You're correct about the Tome extractor. I used it to get usb extensions installed when I installed an OS without the card installed. Problem is it looks like all the Ethernet extensions are still there but I’d need a definitive list of what to look for from
Someone to confirm.
