I'm building an old msdos machine for a little kid (very nostalgic).
But I seem to rememeber that there was an issue about the space of the
harddrive. Some kind of limit I don't remember. How large can a ms-dos
partition be?
Per KB Article 118335
http://support.microsoft.com/kb/q118335/
Microsoft MS-DOS versions 4.0 and later allow FDISK to partition hard
disks up to 4 gigabytes (GB) in size. However, the MS-DOS file
allocation table (FAT) file system can support only 2 GB per partition.
Because of this fact, a hard disk between 2 and 4 GB in size must be
broken down into multiple partitions, each of which does not exceed 2 GB.
FAT file system is limited to 65,525 clusters. The size of a cluster
must be a power of 2 and less than 65,536 bytes--this results in a
maximum cluster size of 32,768 bytes (32K). Multiplying the maximum
number of clusters (65,525) by the maximum cluster size (32,768) equals
2 GB.
Note that the hard disk drive must be supported by the computer's ROM
BIOS APIs, which have a 1024-cylinder limitation, in order for FDISK to
partition the hard disk.
