Question : Problem: Address Conflict Detected on Serial Port B

my Compaq Deskpro EP/SB Series has a problem while booting.
I get this error: "1152-Serial Port B Address Conflict Detected" & the lower left corner show
"F1-BOOT"
after pressing F1 the OS start & the PC work without any problem.
the BIOS show this: "Serial Port B 2F8-2FF IRQ3", nothing else on IRQ3
any ideas?

Answer : Problem: Address Conflict Detected on Serial Port B

I didn't find the "Plug and play BIOS" you talked about & so for IRQ3 set to auto.
I did try to play with Serial Port B & changed the "2F8-2FF" to another option (there are 2 options & disable).
it solved the problem.
thanks anyway!
