A few weeks ago, I scoured the web to find jumper settings for my Prime 3B MkII card. Well, after going through all my junk, I have found it. It is attached as a jpeg file. Apologies for the file format. The graphic is rather large so it's probably best to copy into Word or something and print it from there. Feel free to add or subtract my comments below when you place the info on your website. Cheers, Andrew I got this card to add an extra parallel and serial port to my PC. I found that there were several errors in the first table under the heading JUMPER SETTING:. The following shows the correct jumper settings (J3, J4, J7, J8 and J11) to correctly configure the card for extra serial and parallel ports. As normal, there are 3 rows of pins where you can place a jumper to short out 2 of the 3 pins. Unfortunately, the documentation isn't quite clear as to which row is 1, 2 and 3. So I have used the simple graphic below to show the correct jumper position for the various functions. The 3 rows of dots are exactly as laid out if the Prime 3B MkII board was placed flat on the table with the ISA contacts along the bottom. The 1st column of dots on the left is J1. The last column of dots is J11. The asterisks represent a pair of pins being shorted out by the jumper. ........... ........... ........... 123456789|| | - 11 - 10 J3 - UART1: Enabled ..*........ ..*........ ...........

Currently, a 100MB Zip drive and an HP scanner are attached to the parallel port (LPT2) on this card. They appear to be working fine, so I am unable to verify whether LPT2 has been set to ECP or EPP (this involves J5 & J6). I'm not sure what the differences are between ECP and EPP but there was no difference in scanner and Zip drive performance when I configured the printer IO setting to either ECP or EPP. Below is my current configuration to set up COM2 and LPT2 on my PC: **.*.*..*** *********** ..*.*.**... 123456789|| | - 11 - 10
