The documentation in the Net4801 manual says that you can directly feed +5 into pin 4. What I'm wondering about is whether I should also feed +12 into pin 3.

Does VPWR provide >power for anything, and should I power it with +12 (for instance, the >disk power connectors, the PCI card connector, etc...)? You should double check with Soren before you feed anything into the 5V pin, I don't know if the PSU circuits will like that. You can feed the board on the 12V pin, (same V-range as on the DC plug) which I belive is _after_ the input protection circuitry, so JP10 is not reverse polarity protected. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 [EMAIL PROTECTED] | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
