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",

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
