Hi, In FC4 release note, Pentium M was not listed as a supported processor in i386 family. But I guess it may be supported. Can you let me know if my guess is correct? Currently, I had problem that FC4 installation suddenly stopped while installing disk #1 on my laptop IBM ThinkPad T43 using Pentium M - 2GHz. I also wonder if anyone has the same problem or know what it is? Thanks for your help. --david le.
