Hi again, folks. I have read about Golden Bow's VFeature Deluxe, which, for about $90, you can use a hard disk as a single virtual drive, even though its size exceeds 32 megabytes. And there are other brands of device drivers that do the same. Is there one in the public domain or that is shareware? thanckx.

Compaq's version of MS-DOS/PC-DOS (both 3.1 and 3.2, don't know about the earlier versions) provides a device driver "enhdisk.sys" which permits access to more than one DOS partition on a hard disk. To complement that, their "fdisk" permits creation of several DOS partitions, and lets you designate which partition to boot from. Thus, you could split up a 60MB disk into two partitions, and access the first one as C: and the second one as D:. You could even bind the two into one directory hierarchy with the DOS 3.x command "join", which acts somewhat like UNIX "mount". Wolf Paul ihnp4!killer!dcs!wnp

PC-DOS 3.3 supports primary and extended DOS partitions. Each physical disk must have one primary partition. The primary partition is limited to 32 Mbytes. Each disk may have up to 3 extended partitions. The size of extended partitions is limited only by the size of the physical disk. COMPAQ's MS-DOS 3.31 has a similar feature
