Problem: Is it possible to load PCQLinux 2007 on a partition where Win XP had been installed earlier?

Solution: Primarily No. Windows XP runs on FAT-32 or NTFS partition. For PCQLinux 2007, you should have one Linux partition and one swap partition. Warning: PCQLinux 2007 does not have customized installation option. For desktop type, it would take around 12 GB. So, keep at least 10 to 15 GB space.

Secondly, the installer will give you an option to use the free space to create layout. Choose that option. But on the existing partition, you should have adequate free space. Not sure if this option would work for you when you have a NTFS partition where you had Win XP earlier.
So our advice is go with the first option.

Problem: What is the recommended configuration for PCQLinux 2007 installation? Will it work on P III with 192 MB RAM. While attempting installation, the system shows a message stating RAM  inadequate for Graphics. My XP installation is in NTFS and I am attempting Linux on the FAT partition that has a free space of about 12 GB.Is it Ok?

Solution: The PCQLinux 2007 desktop is based on Fedora Core 6. So the hardware requirements needed for the same are
specified in section 6.3 at http://fedora.redhat.com/docs/release-notes/fc6/en_US/sn-ArchSpecific.html

For PCQLinux 2007 Enterprise (though based on CentOS 4.4), it is difficult to list down the specs as it is meant to be run as a host system for virtualized guests. So lots of RAM (minimum 1 GB) and a processor greater than 1 GHz would be needed. The graphics card should not matter, but a faster hard disk would definitely do.

Problem: After installation of the server without any errors, I am unable get the desktop window after startx command. I am using Compaq, Intel PIII 256 MB RAM system. What should I do to overcome this?

Solution: Server version does not have XWindows included. You can only run the X through a remote SSH terminal. Refer to the article on Virtualization with VirtualBox, page 80, March 2007, PCQuest.
