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.
