I've recently acquired at 286-12 system without docs. What I need to find is the (probable) function of the jumpers. Here is what I know about the system: 286-12 VLSI Chipset Phoenix Bios 3.10 Made in Taiwan ROC There's a sticker on the board with RN8910 on it It appears to accept up to 1 meg of 41256s or 4 meg of 44256 or 1x9 SIPPs There are 7 (?) jumpers (what I'd like to know about): J1 - adjacent BIOS (for adjusting bios size?) J2 - \ J3 - - adjacent VLSI chip VL82C102A J4 - / J5 - Non Existent (at least I can't find it :) J6 - In the vicinity of the CPU J7 - \ J8 - - Near the keyboard/CMOS area There are also 3 connectors (other than the Front Panel stuff) CN1 - Mystery 4 pin between CMOS and CN2 CN2 - Keyboard connector CN3 - Power Any information that can be added to this would be helpful -- -- Kevin Fowler / kevinf@agora.rain.com ------------------------------------
