They set up their MS-DOS partitions as the first partition on their HD and Xenix on the rest. Xenix also has an fdisk program but you need to use DOS fdisk to work with DOS partitions (other than change the active partition). Roger Knopf SCO Consulting Services disclaimer: the usual

Roger Knopf (SCO Consulting Services) replies: rM>They set up their MS-DOS partitions as the first partition on rM>their HD and Xenix on the rest. Or the second if they like. The second partition can be as large as desired, so long as it is divided into logical drives such that no single logical drive is > 32M. This is true for MS DOS 3.3. Other versions and OEM MS DOS's may have different capabilities. Of course, it may be that this "extended dos" partition might not be accessable from a Xenix/Dos bridge -- but that question wasn't asked. --WmP-- --- ~ DeLuxe 1.11a19 #3744 william.pipher@canremote.uucp

My question is ku>this: MS-DOS 3.3 and earlier versions were only able to deal with 32MB partitions on a hard drive, although aftermarket drivers like V- Feature Deluxe, Speedstore, and Disk Manager (Mangler) allowed extended partitions greater than 32 MB. ku>What do MS-DOS users do when they want to use a disk larger than 32 ku>MB? Do they partition the physical disk into many logical disks of ku>32MB or smaller? Do they use a seperate device driver that uses ku>memory? [Perhaps do they abandon MS-DOS in favour of Xenix? :-)] Larger disks can be partitioned into primary and extended DOS partitions using FDISK, and FDISK allows logical drive creation of drives up to 32 MB (DOS 3.3). Other "FDISK"s like NEC's, Compaq's, and some others, support large partitions, greater than 32MB, as does messy-dos 4.XX. ku>What do people do when they want to use a large disk for both MS-DOS ku>and Xenix?

Does the Xenix ku>version of this program have the ability to set up partitions on ku>MS-DOS disks? XENIX supports this. What you have to do is first create the DOS partitions using the DOS FDISK. You must make sure that the DOS partition is not the active partition, otherwise XENIX won't boot. Then install the XENIX, and you'll be OK. If you create a primary and extended DOS partition, XENIX won't be able to access the extended DOS partition. I don't know if XENIX can access the pri- mary partitions greater than 32 MB.
