- Usage: Activate [-d] [-l] [partition #]
-
- -d: Deactivate given partition #
- -l: List partition Table(s)
- # : Number of partition to (De)Activate
-
- if no command line params are given -l is assumed
-
-
- This is a fairly simple program to switch between the various partitions
- you might want to boot off on your hard disk(s). It provides a means of
- setting / resetting the bootable flag on your partitions without having
- to resort to fdisk (which has the potential to do a lot of damage!)
-
- USE THIS PROGRAM AT YOUR OWN RISK! I make no guarentees that it will
- not damage your data - all I will say is that it has done no harm to my
- system - yet! My own setup is with IDE drives: either 1 Quantum LP240,
- or 2 Seagate ST-157A's, depending on whether I'm using Coherent, DOS,
- or Linux - I've had no trouble with this configuration - I know absolutely
- nothing about how non-IDE drives might behave.
-
- The source code is, hopefully, fairly portable. I originally wrote it
- under Turbo C++ v3.0, then worked on a *nix based version under Coherent
- v4.0.0. The only routines which are implementation dependant are stored
- seperately in the act-dos.c and act-ndos.c files (for MS-DOS and non-DOS
- systems respectively). These consist of the routines for accessing the
- hard disk(s). The DOS version uses the TC biosdisk() routine which
- accesses the drives via int 13h.
-
- The *nix version reads / writes to the hard drive by simply opening the
- drive's device (in my case /dev/rat0x, replace this with whatever is
- appropriate) and using fread() / fwrite(); The determine_number_of_drives()
- function is a bit of a 'cop-out', rather than trying to detect how many
- drives are attached to the system I simply return a pre-defined constant -
- set this (NUM_DRIVES) to whatever is appropriate.
-
- Everything you need to configure the program should be in the config.h
- file, simply set up the correct number of drives, and (for *nix) their
- names, then just compile.
-
- The program allows for 4 (primary) partitions on each drive - if you enter
- too large a partition number (say 9 on a 2 drive system) it will abort.
- It also only allows you to set 1 partition per drive as active - it will
- disable all partitions on the relevant drive first, then make the given
- partition active. This can be changed by playing with the for-loop around
- the '/* Deactivate all first */' comment.
-
-
- This is the first (hopefully) useful program I've written for *nix, so
- I'm sure there's plenty of room for improvement :-) I'd greatly appreciate
- any comments, and suggestions (even flames!) via the email addresses above
- - the midir and ccvax addresses are only good until mid summer 1993, the
- bermuda address has a habit of bouncing mail not sent using SMTP, and I
- have yet to receive any non-Fidonet mail at the fido address, so if you
- _really_ want to contact me you can resort to snail-mail to:
