- What is PARTFILT?
- ----------------
-
- PARTFILT.flt is a filter device driver for OS/2 that makes it possible to
- load an IFS for linux partitions. (Without this filter you must patch the
- partition table. On many systems doing so may cause LILO to fail.)
-
- HK: The filter now is NOT specific for Linux.
-
- In addition this driver is capable to control in what order drive letters
- are assigned to partitions on fixed disks. It will also allow you to access
- hidden primary partitions under OS/2.
-
- The goal of this filter is to allow you to use ext2-os2.ifs without breaking
- anything else... :-)
-
- NOTE: You need ext2-os2.ifs to access the files on a linux (ext2) partition.
-
- Conditions of use:
- ------------------
-
- You are free to use the filter in any way you wish to, free of charge. I
- would however like it very much if you can drop me a note on a postcard.
- The source code is available under the GPL license. (If you want to use
- the source, but not under GPL, contect me and we can work out something.)

-
- How it works:
- -------------
-
- A virtual fixed disk is created for each partition under control of the driver.
- These virtual fixed disks each contain one extended partition with a logical
- drive in it. Since OS2DASD.DMD that controls fixed disks first assigns drive
- letters to primary partitions the virtual partitions are tacked on at the end
- of allocated drive letters. (To control the mounting order of all partitions
- OS2DASD is prevented from directly accessing the fixed disks and the filter
- presents it with an alternate list of partitions.)
-
- Installing the filter:
- ----------------------
-
- Add a line:
-
- BASEDEV= PARTFILT.FLT <options>
-
- to your config.sys file. The following command line options are allowed:
-
- /Q Quiet install. Prevents the filter from displaying messages.
- /V Verbose install. Displays some diagnostic messages.
- /W Allows the virtual partitions to be written to.
- /A Virtualize all partitions found. The only good reason to use
- this is along with the /M option when you want to control
- the mounting order of all the partitions. You must use the
- /W option if you use the /A option; otherwise OS/2 may crash
- when it tries to write to the partition.
- PLEASE NOTE: Using the /A option may change your drive
- letters causing the your system to be unbootable. Use
- the /M option together with /A. (This may change in the
- future.
-
- /M <mount list> Mounts the partitions in the order specified in the mount
- list, which should be a list of numbers separated by commas.
- The partitions are numbered 0 on a first come basis. (Not
- the order OS/2 uses.)
-
- --------- ADDED BY HENK KELDER ------------------------------------------
- /P <partition types>
- Specifies which partition types to virtualize.
- Must be specified as hexadecimal numbers.
- for FAT32 use /P 0B. for Linux use /P 83.
- If NO /P option is specified, PARTFILT will not load.

- If something goes wrong:
- ------------------------
-
- I do not accept any repsonsability for any damage that this driver may
- cause. (Remember, you installed it...) I would like to hear about it so that
- I can try to fix it.
-
- Contacting me:
- --------------
-
- If you have ideas for the driver or feel like general discussion or whatever
- you can contact me at vdwest@quark.cs.sun.ac.za. That address will remain
- valid until November 95. After that please use the snail mail address.
