Hello Guys,

so everyone knows what happened and what i did:

after the weekend i startet the machine and the first black screen there it loads the phoenix bios and says

cpu = 486DX2 66 Mhz
0000640K System Ram passed
0007168K Extended RAM Passed
System Bios shadowed
Video Bios shadowed
UMB upper limit segment adress F88A
System Cmos checksum bad - run Setup
EXM Configuration error
Keyboard error
Diskette drive A error

so i asked one of the elders and they told me that its a button cell that has to be switched and i have like 1 minute to do so so i got myself a button cell 2330 BR switched it and now it says :

cpu = 486DX2 66 Mhz
0000640K System Ram passed
0007168K Extended RAM Passed
System Bios shadowed
Video Bios shadowed
UMB upper limit segment adress F88A
EXM Configuration error
Keyboard error
Diskette drive A error

so my battery problem is solved but the EXM files are deleted i can argue that it took me longer but i know that it happened i a few seconds elders ;D. when i found a post here on IA that i should have write down the parameters before i changed the battery and yes i didnt do it why didnt know so. does someone has a similiar machine or knows what it could be and help me?

Thanks an best Regards
