Essentially, what this limit comes down to for many new PC's today is NOT any kind of problem with the BIOS, but rather a limitation of the operating system itself! Microsoft® DOS and even Microsoft® Windows95 (the original version) cannot access hard drive partitions over 2.1 GB because of how they actually format the hard drive's clusters! Only by using the so-called 32-bit FAT system can you have a single partition over 2.1 GB.
I don't have an article
about the 2.1 GigaByte Limit right now, however, I suggest you visit
this site:
Western Digital's "tip" article from DEC 1996 on drive size
limitations under... FAT16 vs FAT32.
And...
The
NOV 1996 article on "The other BIOS Limitation!"
