- EFDISK (Extended FDISK) is a disk partitioning program. With EFDISK
- you can create or modify primary partitions of your harddisks.
- EFDISK supports many partition types, howewer you cannot make
- DOS logical drives and extended partitions with it. The original
- FDISK program doesn't allow you to create more than 1 primary
- partition. EFDISK does, therefore it's a powerful tool to help
- installing more operating systems in your PC.
- EFDISK is a support program of MasterBooter.

-
- Note: Playing with partitions is a risky job! Use this program only
- if you know what you're doing!
-
- 1) Installation
-
- You can copy these files (this docs and the executables) together
- wherever you like. This program doesn't need any additional
- settings. Just run it and have fun.
-
- 2) Usage information
-
- For safety:
- 1) Make a system disk: Type: format a: (PRESS ENTER)
- sys c: a: (PRESS ENTER)
- 2) Run the program MRESCUE.COM. Choose the 'Create rescue disk'
- option. It will copy important information about your disks
- and the MRESCUE.COM itself to floppy, so you can restore your
- previous configuration later if necessary.
- 3) Now you can safely run EFDISK. If anything goes wrong, boot
- from the floppy you've just created, run MRESCUE.COM and
- choose 'Restore original configuration'.
- This will reset all modifications.
- Send me a mail if something is not working, and write
- all steps you've done unless I won't be able to correct the
- problem. Thank You!
-
- Before running EFDISK quit all multitasking environments
- (ie. Windows or OS/2 DOS box) and run plain DOS, because
- after the program writes the modifications to your harddisk,
- the system needs to be rebooted.
-
- When executing, EFDISK will gather information about your disks and
- partitions. Then you will be provided a list of all partitions of
- all disks and their parameters. From this list you can choose the
- partition entry you want to change.
-
- When you select a partition, EFDISK will ask several questions.
- These are:
- - The hexadecimal type ID of the partition. EFDISK will show you
- the most common types and their IDs.
- - Starting cylinder number of partition (the minimum is 0).
- If the previous partition is ending on cylinder 'x' then set
- this to 'x+1'. This number is decimal.
- - Ending cylinder number of partition. EFDISK will show you the
- maximum cylinder number available for the actual harddisk.
-
- The number of heads and sectors per track vaules are determined
- automatically for each disk, you don't have to mess with them.
-
- Pressing SPACE will activate the highlighted partition. It won't
- do anything, if the highlighted partition is not on the first
- harddisk.
-
- After preparing all partition entries, press F10 to save the new
- partition table to disk.
-
- !! Usage note: - EFDISK doesn't check for partition errors! It's not an
- !! 'intelligent' program. You have total freedom to set all
- !! parameters, even if they are incorrect or redundant!
- !! - This version can be used with max. two hard drives only!
-
- 3) Notes about partitioning
-
- - If there's data on your harddisk then create backups of your
- partition tables with MRESCUE.
- - You can have only one active partition in your first harddisk's
- partition table. If you activate a artition, EFDISK will
- automatically clear the other partitions' 'active' flag.
- !! - Don't use EFDISK to resize or move such existing partitions that
- !! contains data you need!

-
- Version:
-
- 1.1 - First official release in the MasterBooter package
-
- 1.2 - If the starting cylinder of a partition was 0, then the
- 'relative starting sector' and 'number of sectors' value
- in the partition table were incorrect. Now they're correct.
-
- 1.3 - Fixed a small bug, that sometimes caused incorrect 'number
- of sectors' value.
-
- 1.4 - Now the 'Space' key can be used to activate a partition,
- so no need to retype all parameters.
- With large hard drives, sometimes the partition sizes were
- incorrect. Now they are always correct.

- └───────────────────────┘
-
- A harddisk can contain up to four primary partitions. The partition
- table (which resides in the very first sector of your harddisk)
- describes the type, bootability and starting/ending cylinder number
- of the partitions. In bootable partitions, the first sector is
- always the so called 'boot sector' which contains a small OS loader.
- In these partitions you can install any operating system in theory.
- But in the real world some operating systems don't allow you to
- create more than one primary partition, or to boot another operating
- system. So creating multiple primary partitions and choosing the
- operating system at boot time was quite difficult.
- That's why I wrote EFDISK and MasterBooter.
-
- Note: DOS based systems (therefore Windows 95) can only boot from
- a primary partition of the first harddisk!
