If your drive is larger than 8.4 Gbytes, the capacity may exceed the limits of your system BIOS and operating system. Most system BIOSs cannot support ATA drives this large. DOS and Windows operating systems limit the drive capacity to 8.4 Gbytes per physical drive and 2 Gbytes per partition. Because of these limitations, a 32-bit file allocation table (FAT32) is required to acheive full capacity of your drive, beyond 8.4 Gbytes. To acheive full capacity of your drive, you will need BIOS support for drives greater than 8.4 Gbytes and a Windows operating system that supports FAT32. This support is available by way of the following methods:
* A third party device driver, such as DiscWizard Starter Edition (DiscWizard Starter Edition is provided on the DiscWizard diskette included with your drive)
* An intelligent ATA Host Adapter
* A system BIOS upgrade
Originally the laptop is shipped with a preinstalled Windows XP with a single 30GB partition.
So normally you can have 1 large partition. If you want to install 2 operating systems, the boot files must be in the first 8GB of your hard drive. Your normal files can be in an extended partition.
