2nd, I have dual boot (XP+Fedora2) installed on my notebook, they have been working pretty well for over 2 years, only this time, I don't know what's wrong with the RHEL bootloader;
3rd, I think VMWare needs to share physical memory with the host system, that it, if I allocate 1GB memory to VMWare, than I couldn't use it for the host system. Because I'm going to run pretty large and memory consuming circuit design and simulation CAD tools on my Linux and XP (XP also for playing games sometimes:), I don't think VMWare is a good choice for me.
