Some friend gave a 286 computer some years ago. This computer run ok but i couldn't configure the MFM HDD and have not diskettes so i only accessed to Bios and tried some HDD types with no luck. I noticed then that it had a varta battery (not leaking) so i remove it and never tested the computer until now.
I tried to boot and have not POST and no beeps. I removed all cards and connected an ISA debug card and all LEDs light up except RST led as it shoud. So voltages, clock and everything there seems to be fine. But is stuck in BIOS error code "03". The BIOS is Award.
I read on the documentation this could be for different reasons:
- Disable NMI,PIE,AIE,UEI,SQWV
-Disable video, parity checking, DMA
-Reset math coprocessor
-Clear all page registers, CMOS shutdown byte
-Init timer 0,1 and 2, set EISA timer
-Initialize DMA controllers 0 and 1
-Initialize interrupt controllers 0 and 1
- Initialize EISA extended registers
I tried resitting all ram chips and everything and it not worked. Also tried to apply power to battery pins with an adjustable power supply (3.6v). I will try with a coin battery but should not be the issue.
Do you know what more to try? Thanks
