[I don't believe in the li I would like to know the limits of PC-DOS 3.1, eg. 1) How large a file will DOS support 2) How large a Disk Drive will Dos support... If anyone has any interesting fact along these lines I would love to hear them. If you don't think it's worthy of the net, personal e-mail is fine. I will post a summary if this gets really interesting. -- ----------- Scott Presnell Eidgnoessische Technische Hochschule, Zuerich (ETH-Zentrum) Labor Fuer Organische Chemie Universitaetsstrasse 16 CH-8092 Zuerich Switzerland. uucp: ...seismo!mcvax!cernvax!ethz!srp (srp@ethz.uucp) earn/bitnet: Benner@CZHETH5A

Several companies (such as Emerald and Express Systems) have developed products (hard/soft ware) that allow DOS to access much larger "stuff". If you don't have one of these, and have a disk over 32meg, you MUST divide it into several partitions, each <= 32meg.

I can live with a partitioning scheme (it means that any one file can't go past the 32Meg partition boundary), and I may have to play games with the "active" drive letter. OK, but I want to have all my disk space online AT ONCE. The standard PCDOS FDISK allows only one DOS partition, and the IBM BIOS only supports one active partition per drive. How do I get more than one partition active at once? Is there a public domain device driver I can install to gain access to more than one partition?

You can also partition your disk drive into many DOS volumes, with optional password security for each volume. I have been using this with my AT using a maxtor 1065 hard disk (55 Mbytes formatted) for many weeks now and have had no problems. It's great to see chkdsk show 55 Mbytes available! Address: Golden Bow Systems P.O. Box 3039 San Diego, Calif. 92103 (619) 298-9349 Vfeature Deluxe costs $120 This is the same software described in a recent PC Tech Journal, and it is used by Emerald, et. al. I have no connection with Golden Bow except as a very satisfied customer. -- Bill Marsh, Naval Ocean Systems Center, San Diego, CA {arpa,mil}net: bmarsh@nosc uucp: {ihnp4,akgua,decvax,dcdwest,ucbvax}!sdcsvax!noscvax!bmarsh "If everything seems to be coming your way, you're probably in the wrong lane."
