i just played a little with my EC1834 in the last few days.
1. Regarding the modified keyboard ROM: I decided today, i do not longer intend to improve this version, as i found it too cumbersome to program U8821M in assembler. Just want to remind you, that some special keys wont work, like "print screen"(i think you might never need those). Also, sometimes my machine boots displaying "301 Keyboard error" but when i hit F1 it works. I did not find the bug after several days of looking so i decided to give up now.
2. I also soldered an ISA slot onto my mainboard and use a VGA adapter Tseng ET3000AX. It only works with newest BIOS ROM version 731/732.
Starting from the front of the board with #1, my switch is set like this:
#1 right, #2 right, #3 right, #4 left, #5 right, #6right, #7 left, #8 right. I think only #5 and #6 switches are relevant to graphics.
I dont know which jumpers you mean by WD1-WD5 but i suppose its those white DIP switches.
