Access to ext4 & FAT32 partitions (Fedora 10)

[Jay Mistry]

On a new install of Fedora 10 on a home desktop PC, how can one enable
access to Windows XP (FAT32) and Ubuntu (ext4) partitions from within
Fedora (using GNOME 2.24 desktop)?
The Linux installs (Fedora 10 and Ubuntu 9.04, both i386) are on a
separate HD than Windows, and I boot into them from the NT bootloader.

I was able to access (mount) the NTFS partitions of Windows XP after
installing ntfs-3g and ntfs-config.

Thanks,

Jay
