Since I'd like to keep the hardware minimally modified, your idea of using a system extension in order to enable the soft-power VIA bit is more than adequate and I have to say a BIG THANK YOU!!!
Now, here come the bad news: it doesn't work on the SE/30
I tried first the "universal" second version, but the testpoint keeps at 5V all the time... then I did the ResEdit mod to the first version -- the sysv check app said:
so I changed the resource value to 220B 089B -- let's hope I did the binary math right! But again, to no avail...
Let's hope that line isn't just hardwired to 5V...
Anyway, there are some good news today: I'm posting this from the SE/30!!! connected to WiFi Internet with the help of my sister's sparkling MacBook Pro. This site works surprisingly well on Netscape 3.01, I downloaded the SysV extensions on it. I'm using System 7.5.5, OpenTransport 1.1, an (expensive) Asante MacNIC II/E card and 20M of RAM. TCP/IP uses DHCP.
On the MBP side, there's Lion (10.7.3) and Internet Sharing from AirPort to Ethernet -- the latter set manually, with the Airport IP as Router/Gateway. The WiFi itself comes from my MacMini sharing my CableModem Internet connection (!)
Back to our problem, I may try on the IIx (with a hacked PSU) connecting the VIA port to the NMI line, and checking with MACSbug what code is being executed at the very moment of shutdown...
