My Tandy 2500 XL says "Invalid configuration information - please run SETUP program"

Few times runned it. When trying set HDD params in SETUPXL.COM utility it says Divide overflow. Hard drive is PLUS IMPULSE 52 LP (52 MB). Same error without HDD attached.

Also updated ram 1 MB -> 4 MB but that error was before ram update. (some reason extended ram goes to 3072 KB automatically)

Anyone help? Want install DOS + Windows to HDD but cant set HDD specs to bios utility.

Dallas chip reworked and it uses now CR2032 battery.

"Invalid configuration information - please run SETUP program" should go away after going into SETUP and saving
