I think you might have the wrong Asante installer. I just got one of these cards, and it needs the AsanteFAST 10/100 installer, and the AsanteFAST 10/100 installer didn't need the card to be present to install the driver.

Did you just replace the 20MHz oscillator on the main card, or did you also replace the one on the connector board? Between the connector and the AT&T T7220 chip. Pretty much anything that stops the transmit path from working, while the receive path is still working, can result in a blinking...

The ones I have don't have this issue, so it isn't applicable to them. I have a MacCon for SE Rev C, and a MacCon for IIsi SE30 Rev C2. I haven't had any issues with these cards and modern ethernet switches. Cards that have this compatibility problem have a DP83902, and automatic media...

I have some DaynaPORT E/LC-M cards, which is actually quite a good card for computers with an LC PDS slot. They have the DP83934 SONIC-T chipset, which is quite a good 10Mb ethernet chipset, and is compatible with the Apple Ethernet LC Card. However coax ethernet is a pain these days, and for...

That chip is the ROM, it is the one with S9406AN on it that I would check the pins on. I think S9406AN is a date code (probably 1994 week 6), under the label it will have "DP83902AV" and "ST-NIC™", that is the ethernet chip. The label sticking over the edges might be obscuring something. The...

Just in case anyone else with a DaynaPort E/II-T is looking for information, this version of the DaynaPort E/II-T uses the "St." version of the driver. It also works with Apple's driver, but Apple's driver doesn't utilize all the RAM on the card.

Just looking through the resources for the installer, installing "DaynaPORT II" installs a driver for board ID 298, which is what I believe the DaynaPORT E/II-T is, the EtherPort II has that board ID. Installing the "DaynaPORT (St.) II" installs a driver for board ID 8. I have two of the...

Installing a resource in to the System file was typical, up until later System 7 versions and NSI 1.5. Those added a mechanism where the 'enet' resource can be put in to an extension file, which is much neater. However a lot of drivers and installers were never revised to work that way. If you...

I don't have the manual, but that card looks like a later revision of the Dayna/Kinetics/Novell EtherPort II, with coax swapped for 10base-T. Other than the differences for coax vs 10base-T, it seems to have all the same components in a similar but revised circuit board layout. That would make...

Is this one of those cards that has a big ASIC (Farallon 3170828-00-01), a ROM, and 2 SRAM chips? Loopback failing in the controller sounds like that ASIC has failed, particularly with RAM test passing and register access passing. Are you definitely running the test with the card not active for...

I have two Farallon PN590a-TN NuBus ethernet cards that only have coax and AUI connectors, and I was curious if it would be possible to add 10base-T support by populating the empty spaces on the board. While it is easy enough to pick up cheap AUI 10base-T transceivers on eBay, they often don't...

These cards are only 10Mb half duplex. If your ethernet switch has a way to turn off Auto MDI-X, that should help. If you are using MacTCP, it doesn't support DHCP. You would need to have BOOTP support on your network, or manually configure the IP address. With a Quadra 700, you might want to...

Here is a mod for the MCNB/MCiNB that hardwires it for 10base-T. It involves cutting a trace, then soldering a link between two points. Pictures attached. This mod is cutting the automatic AUI/TPI link between U1 and UA5, then tying the AUI/TPI input on UA5 to GND. C8 and C9 can also optionally...

Here is a schematic for the relevant parts of the MCNB/MCiNB, picture also attached. Still working out what to do with this one. The input to the 26LS32 could be hard wired, like with the MCiLC, however that would completely disable AUI. The alternative would be something like cutting the...

I replaced R17 on two DaynaPORT E/II-3 cards, changing it from 100K to 200K, and they both now work with my TP-LINK TL-SG1016DE ethernet switch. Image with the location of R17 highlighted attached. Larger resistor values like 220K, 270K, or higher, should also work.

This is by no means the general case, there are cards like the Asante MacCon+IIET that have automatic media detection and don't have this problem. The problem cards I've seen all use the DP83902, which doesn't have built in support for automatic media selection, and then try to add on 10base-T...

Here is a picture of an unmodified DaynaPORT E/II-3, and a schematic I've made. The link detection circuit seems similar to the Asante MC3NB, with R17 setting the timing for link detection. I've ordered some surface mount resistors, when they arrive I will try changing R17 to 220K. There are...

Here is what I have done to fix an Asante MCiLC. The card I have looks like it was designed for both TP and coax, but then a version of it was made with the coax components removed. Unfortunately that version still has the media detection and switching circuitry present, which suffers from...

Here are schematics I've made of the media sections of the Rev B2 and Rev G To do a full conversion of a Rev G to remove coax and the problematic TP link detection circuit, it looks like the AUI/TPI pin of the DP83902 can be connected to the AUI detection circuit by removing the link at R45...

Another solution, the problematic link detection circuit can be made to work by changing R28 from 36K to 220K. This increases the time allowed between detected link pulses to be long enough to allow for Auto MDI-X. I've tested this on a Rev B2 and a Rev G card, with a TP-Link TL-SG1016DE...
