rom1, rom2 & erom not found

I am trying to get the right configuration of the pcsx2 (emulator for PS2), but when I got everything else that I need (I think), when I tried to run a CD/DVD it says rom2, rom2 and erom not found. I need help about how I can fix this. Thanks a lot!

What are your computer specs? (Operating System, RAM, Processor, Graphics Card).Did you download PCSX2 from the official website?

Microsoft Windows XP
CPU 1.80GHz
1.79GHz, 496MB RAM
Mobile Intel(R) Pentium(R) 4And yes, I downloaded it from the official site. Regarding the BIOS, I copied the BIOS of another PCSX2 that I dowbnloaded beforehand and uninstalled after so I could install the version/file I got from the original site. I had my DirextX updated (have the d3dx9_40.dll & ddx10_40.dll in the system 32 folder in Windows, thus I had a successful update of DX). Does the C++ I hear about have any effect? Bec. that I may not have looked upon yet.

I think these are part of the BIOS files. You'll need to find them and put them in the BIOS folder.

I thought it may be that, too. But I don't know exactly the BIOS that I need to fix it so I asked for help here.
