Okay,

I had a working (but maybe tried 1-2 years ago) Zida 5DXP ( HW Revision 1.0, BIOS Revision 2.10) with P166 on it. I decided to gift it to my friend. Changed cpu to 133. Also adjusted jumpers acccording to manual.

Had no luck to get a video signal. If i try 20 times to boot. Only one time i get picture.

And thought Dallas must gone off. And noticed board has a free space for coin cell thought for CR2032. Desoldered dallas and installed a CR2032 battery holder to mobo.

Now every time i boot i got signal. But keeps restarting when it says "press del for bios setup"

Removed CR2023
removed everything but Cpu ram psu vga

tried both clear and normal battery modes.

re-check all jumper settings and set them again.

no luck.

Does this battery space not for real? or not for cr2032?
Should i mod Dallas and put it back?

Hi oguzog,

Be aware that the Dallas block contains the RTC chip, the CMOS memory, a clock crystal, and a coin cell battery. So without it you don’t have an RTC with CMOS RAM and the board won’t boot.

Here is a great video from Necroware that shows in detail, what you can do if your board has provisions for a CR2032 battery.

Well i have open two holes on dallas and see that it shows over 3volts.

Put it back and saw one trace has been cut off.

make bridge. remove cr2023

now it works. And saves settings too.
