yes could check the card on the back side.
Found already these settings so far:
JP3 Diskette drive / FDC bios??? (one drive gone, detects only one with a disk 80 error on boot. (no prrr sound anymore)
JP4 ???
JP6 LPT1 port adress: 1-2 = 0378 2-3 = 03BC
JP5 LPT1 ON / OFF 1-2 = ON 2-3 = OFF
JP2 RTC???
JP1 FDC BIOS 1-2= ON, 2-3= OFF (sees 2 drives without prrr, so think booting in low-density mode without bios)
JP10 ???
JP8 ???
JP7 COM 1 / COM1 is gone.
JP9 ???
JP16 = COM 1 ON / OFF Jumper ON= ON Jumper OFF= Disabled
JP15 - COM 2 / Gameport?
JP14 = Drive B: is 1.44MB (jumper JP14 removed, JP13 removed) (Drive B: is 720KB JP14 Installed, JP13 removed)
JP13 = Drive B: is 1.2MB (jumper JP14 removed, JP13 installed)
JP12 = Drive A: is 1.44MB (jumper JP12 removed, JP11 removed) (Drive A: is 720KB JP12 Installed, JP11 removed)
JP11 = Drive A: is 1.2MB (jumper JP12 removed, JP11 installed)
(360 KB drive will ignore these settings)
The rest have to check with the program checkit to see if address suddently changes.
Also think com2 doesnt work..
Perhaps because of no UMC UM8250B chip in the empty socket?
Gameport enable / disable doesnt show on boot. Think i only can see its active or not with a program like check it.
Could be that COM2 was an extra option back in the day, so only com1 was available on the card.
I need one serial connection for the mouse. Com2 can be getting it to work. Only did not found a solution to adopt a DB25 serial (26 pin) internal on the card to an DB9 (9 pin serial as output.)
