Adding ":" after the drive letter (as a capital letter) is a thing you usually see in any documentation, like "this erases you C: drive" or "check floppy in A: and B: to make sure they are present". > The correct word as displayed in the fdisk program is 'logical dos > drives' just the way i have it. Okay, then "Laufwerk" and "drive" are corresponding correctly. Then it's a "logical drive inside an extended DOS partition". I will remember this, thanks for checking! > back in win3.1 days a 20MG hard drive was the largest made at the time. I'm _sure_ it was a 20MB hard disk, maybe just a typo? :-) And for the rewrite: > The Microsoft/Windows fdisk program is used to allocate partitions on > the hard drive. This program allocated two types of partitions “primary > dos partition” and “extended dos partition”.

You should have DOS in caps always, as in "primary DOS partition". > An alternate method is to allocate an “extended > dos partition” and then sub-divide it into logical dos drives lettered > C, D, E, F. And it is possible to have a bootable system without a primary DOS partition? I hardly can imagine that - but don't bet on my opinion, I've NEVER used any "Windows", so I'm honestly just guessing. A typical "multi-drive" setting would contain a primary DOS partition C:, and an extended DOS partition containing the logical drives D:, E: and F: (for your 4-drive example). > The FreeBSD ‘disk label’ program is used to sub-divide the slice into > smaller chunks called partitions.

I'm sure you wanted to say 20MB - megaBytes. :-) > The FreeBSD fdisk program has option to > write a simple boot menu program to the MBR. Its called the "FreeBSD > boot manager". The program "boot0cfg" does this. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
