Keep in mind, you'll need to partition a 4GB stick into two 2 GB partitions as DOS has a 2 GB Maximum partition size and without an additional driver for FAT32, it won't recognize FAT32 drives that could otherwise be larger.

And there dies another myth ... Never thought off someone considering to build a USB driver for DOS.

No chance. You cannot access files of that size, nor file systems, when using pure (poor) DOS. Compression programs will stop at 2GB normally. You can do a 1GB split, e.g., and according partitions on USB stick.
