Hi,Bart
My win98se is freshly installed. via copying the win98se setup files to the ssd C:\WIN98SE(c: dos6.22 and upl software already installed),then run SETUP. If SSD is used, after the win98 setup first reboot ,must be use win98 boot floppy disk boot system ,then type:SYS A:C:,after the above operations ,the win98 system installation can be completed.
In win98se system ,run floppy disc :upl 3.06 1 and 2,then use win98 boot floppy disk(your win98updated files already copyed to this fdd a:\) boot system ,then type:updupdated.bat. reboot,ok!
I can use UPL in win98 now .
Upper mem :total 196.544k used 32.704k free 163.840k . (B10 NOT INSTALLED,I DON’T have any options installkey ).
The confusion is that the upl run in win98 system seems instability.
Best Regads.

Hi CSKG,

Could you try using one of my images? just want to rule out a bad windows install. You can use paragon to flash the image on the cf card and then restoring the mbr like you mentioned with sys c:

I’ll set up a test with your type of motherboard over the weekend to judge instability.

Kind regards,
Bart

Hi,Bart,
Yesterday i mod the autoexec.bat and config.sys,Since then ,the system seems to be very stable.
Autoexec.bat :
delete<mode con codepage prepare=((850) C:\WINDOWS\COMMAND\ega.cpi)
mode con codepage select=850
keyb be>
Config.sys:
delete<Country=032,850,C:\WINDOWS\COMMAND\country. sys>
May be mod to <keyb us> <country 001,850>,it also will work.I didn't try.
Kind regards,
CSKG

Hello ,

Input relay with bad contact ??? and which is the right one , K3 ? On the analog/analyser pcb are no designations for the parts .
Kind regards , Alexander .

Hi Alexander,

First thing i would check is the selftest, if you are able to run it, it requires the B10 option.

Perhaps there you could find more clues to what search next.

Kind Regards,

Bart

Hello Bart ,
thank you for your answer , but the UPL made a selfrepair . Very important is , to resolder the fuse holder from the 5V / 5A fuse . I had smoke from my older UPL and it was the fuse on the pcb .
I measured channel one with the Victor 1khz generator and channel two with the UPL .
Kind reards , Alexander .
