Have XP on a Toahiba laptop. Want to keep it for the spouse to use (she has not converted yet but I'm hopeful). Would like to use FC2 since I've used various versions of RH for several years. Have not tried to dual boot this laptop and am aware of the FC2 and XP problems. see http://lwn.net/Articles/86835/

However, I don't know how to downsize the existing XP partition to make room for FC2. What utility should I use? Can the repartitioning be down with some existing Linux utility?

Can I blow XP away and install FC2, leaving room for XP or should I use something to downsize the existing XP partition? I do not have anything like Partition Magic.

Incidentally my hda parameters as reported by fdisk -l /dev/hda are

C = 3,648, H = 255, and S = 63.

The link above says one then uses an example command

linux hda=14593,255,63

I assume mine would be

linuz hda=3648,255,63

Thanks in advance.

If you install XP second you'll have to have a boot disk to get you started back in linux but that's no big deal.
You can set up your partitions for everything during the installation too, including a swap partition and even a FAT32 partition to share if you had the room.
QParted is an equivalent to Partition Magic that would work for you but I'm not sure if it comes with FC2. I use slack and the basic fdisk which is simple and effective.
There's a lot of options. It's just up to you!

People say it's time to move to FC3. (I guess it does not have the FC2 dual boot problem???)
