Infrastructure Software

I download solaris 11 from oracle for several days,sol-11-exp-201011-repo-full-iso-a.zip and sol-11-exp-201011-repo-full-iso-b.zip,then I use winzip to unzip these two files into sol-11-exp-201011-repo-full-iso-a and sol-11-exp-201011-repo-full-iso-b,then I merge these two files into one,I do it as windows OS.
c:\>copy sol-11-exp-201011-repo-full-iso-a/b+sol-11-exp-201011-repo-full-iso-b/b sol.iso

I look sol.iso files,its directory is follows:
repo 4,594,696KB
COPYRIGHT 8K
NOTICES 1,837
README 8k

Then I put sol.iso into DVD disk,then I install it with VMWare Workstation,following is showing information:

Network boot from Intel E1000
CLIENT MAC ADDR: 11 05 32 AD 20 07 GUID: 23423333-21A2-893D-332D-A253CB353212D
PXE-M0F:Exiting Intel PXE ROM.
Operating System not found

I am frustrated with it!!! I cost may days to download Solaris 11,but I can't install it! Where is wrong? Please help me!

Thanks
