The history was this, as far as I know: MS-DOS 2, 1st version with hard disk support; 1 × FAT12 32MB partition MS-DOS 3.0, 1 × FAT16 primary + 1 × extended partition with 1 logical drive, 2 × 32MB partitions, total 64MB MS-DOS 3.3, 1 × FAT16 primary + 1 × extended partition with up to 23 logical drives, total of 24 × 32MB partitions, total 768MB Compaq MS-DOS 3.31, large FAT32 partitions with up to 32 sectors per cluster for partitions up to 2GB IBM PC-DOS 4.0 adopted the Compaq scheme and MS followed suit. (DR-DOS 3.4, the first version, was just before, and I think also used the Compaq scheme.) Windows 95 OSR2 introduced FAT32. The reason was that the number of sectors before a partition was still limited to 64 Ki so the extended partition was needed, in order to provide a new origin in the disk. This I did not know. Anyway, this discussion is going astray from the original problem of Marcos Favero, for FDISK should have created the FAT 16 partitions he requested, whether or not some DOS versions could find all of them.

Re: [Freedos-user] Partition layout
All labels are unique and contain the drive letter. Do you consider DOS, W2K and Warp4 to be obscure? Also every partition has a directory of the form 1_Name_X where X is the drive letter. The one forces it to sort at the top. So from any HDD utility or directory listing I know the physical position of each partition. The users self identity on a computer should not be intricately related to the OS that is in use. WARP4, W2K, DOS? what does that say about the *content* stored by that user? I have an additional challenge. All my HDDs are front panel plug-in. So I have to give each HDD a unique ID that is seen by HDD utilities. If I was cloning or cleaning a drive and got it reversed that would not be good. I have had a HDD utility swap drives 1 and 2 on it's display. Harddrive serial make and model or variant of such is what I use, that way I can see that yes it is from that seagate and not the western digital..

Re: [Freedos-user] Partition layout
Better to label your drive volumes to something other than obscure or drive letters, like DATA, or your name. that way when you in a fdisk program or other OS you can see what is what and not cause an accident.

[Freedos-user] Partition layout
I have always had a single primary C for DOS and W9X, and everything else extended. W2K then puts it's boot files on C. That can cause problems trying to restore the W2K partition from backup. So I created the drive below. I am sure it will wrap. Sorry. The labels include the drive letters, if they boot to their physical position. And that is the challenge. Booting FreeDOS 1.0, the W2K-D primary picks up the letter after any extended partitions. With DRDOS 7.01 Fat32, they hold their physical position. Ideas?

Re: [Freedos-user] Partition layout
I've got a SUSE LINUX Pro 9.3, IBM PC DOS 6.x(drive C:), MS-Win98E(drive C:), IBM Warp 3(drive F:) on /dev/hda and booted using GRUB as a boot manager. GRUB has a number of features for booting most any OS which may help your situation. I hide and unhide various partitions as necessary to get the drive layout configuration. Notice that partition table entries are not sequential. IBM PC DOS 6.x boots as expected as drive C: while /dev/hda2 is hidden; the reverse is used when booting Win98 SE from /dev/hda2 instead of DOS. GRUB has many features one may allow your configuration to work. Here's the fdisk of it.
