- 1. Warnings
- -----------
- vfat-os2 is a FILE SYSTEM DRIVER. Being a driver it runs at the most
- privileged level of the OS/2 operating system, known as "kernel mode".
- IN KERNEL MODE THERE IS NO MORE CRASH PROTECTION. It means that if a
- bug occurs in the driver IT CAN CAUSE A HANG OR A SYSTEM HALT, AND THUS
- CAN CAUSE LOSS OF DATA.
-
- I STRONGLY SUGGEST YOU TO MAKE A BACKUP OF ALL YOUR DATA (EVEN IF THEY
- ARE NOT LOCATED ON A VFAT PARTITION) PRIOR TO USE THIS DRIVER.
- DON'T USE THIS DRIVER ON A PRODUCTION MACHINE, OR IF YOU MANIPULATE
- CRITICAL DATA.
- IF HUMAN LIFE DEPENDS ON YOUR SYSTEM, DON'T INSTALL THIS DRIVER ON IT.
- USE IT AT YOUR OWN RISKS, AND ONLY ON A MACHINE YOU ACCEPT TO CRASH AND
- REINSTALL.
-
-
- 2. Installation instructions
- ----------------------------
-
-
- 2.1 Manual installation of vfat-os2
- -----------------------------------
-
- 1. copy mwdd32.sys in boot drive\OS2 or in boot drive\OS2\BOOT (WARP only)
- 2. add the following line in CONFIG.SYS
-
- BASEDEV=MWDD32.SYS
-
- 3. make a directory to hold vfat-os2 files somewhere but NOT on a VFAT
- partition.
- 4. add this directory at the end of the PATH and LIBPATH statements in
- CONFIG.SYS
- 5. copy the following files to that directory :
- vfat-os2.ifs
- vfat-os2.exe
- vfat_lw.exe
- umount.exe (only if not already installed together with ext2_240
- this version does not use any EMX dll)
- remount.exe (only if not already installed together with ext2_240
- this version does not use any EMX dll)
-
- 6. add the following lines in your CONFIG.SYS
-
- IFS=path\vfat-os2.ifs -cache:256 -errors=continue -VFAT:*
- RUN=path\vfat_lw.exe
-
- 7. if necessary, adjust vfat-os2.ifs command line parameters
-
- Note : In CONFIG.SYS, vfat-os2.ifs MUST be located AFTER the IFS managing the
- boot drive (HPFS.IFS usually).
-
- Note: do not specify a VFAT partition in DISKCACHE statement in the CONFIG.SYS
-
-
- 2.2 Command line options for vfat-os2
- -------------------------------------
-
- vfat-os2 accepts the same command line options as ext2-os2 (whose ext2-support
- is included in vfat-os2.ifs)
-
- see also
- http://www.geocities.com/SiliconValley/Bay/5313/install.html#450
-
- In addition you have to specify which VFAT partition should be supported
-
- to use a list of recognized FAT partition as VFAT:
- -VFAT:<drive letter of your vfat partition><drive letter of second vfat partition>...
-
- to use all recognized FAT partition as VFAT:
- -VFAT:*
-
- to force a FAT partition as VFAT when not automatically recognized:
- -VFAT:C+
-
-
- Currently you can't specify the boot partition as VFAT type.
-
- For example if you like to enable VFAT support for your drive C: add the
- following option to commandline
- -VFAT:C
-
-
- 2.3 EXT2 support in vfat-os2.ifs
- --------------------------------
-
- vfat-os2.ifs include the ext2-os2.ifs version 2.40. To enable it you need to
- add "BASEDEV=EXT2FLT.FLT" to your config.sys
-
-
- 2.4 VFAT_LW.EXE
- ---------------
-
- VFAT_LW.EXE is a replacement of ext2_lw.exe
-
- 2.5 VFAT-OS2.EXE
- ----------------
-
- VFAT-OS2.EXE is a replacement of EXT2-OS2.EXE
-
-
- 3. Read/Write Consideration
- ---------------------------
-
- For safety reason write-support is disabled but can be enabled by one of two ways.
- But don't forget that this version is still beta code and see '1. Warning'.
-
-
- First way:
- add the option '-rw' to the command line of VFAT-OS2.IFS and restart OS/2.
-
- Second way:
- start VFAT-OS2.EXE and enable 'read-write' support on the last page. After checking this option
- Write-support is enabled immediatly for writing/creating files but not yet for creating/removing
- directories on all supported drives (VFAT and EXT2).
- To enable full write-support (same as the '-rw'-option) you have to remount the partition using the
- following command sequence:
-
- 1. remount <drive letter>:
