I have used it for probably two or more years. I would guess it is still available.

Question 4.4: can I finetune the kind of information being logged ? ************************************************ Section 1 Questions about using fsdext2 ************************************************ ================================================ Question 1.1: How do I install fsdext2 ? Answer: 1. Unzip (using -d to restore dir. structure) the .zip file in a directory you want. 2. Run the install.bat script, this copies - vext2d.vxd to the \system directory and - tsdext2.vxd to the \system\iosusbsys directory. 3. Reboot the machine in order for tsdext2.vxd to be loaded. After that it's done. ================================================ ================================================ Question 1.2: How do I mount a partition ? Answer: First run "mount.exe" with no parameters, it will print the partition table which looks like the partition table format when your Limux kernel boots. Note that you cannot mount an "extended partition" (id=5), but only the "logical partitions" in them. To mount use either: - mount /dev/device-you-want h: - mount /dev/device-you-want The first will mount the device on drive h:, the second will use the first available drive letter in the system. ================================================ ================================================ Question 1.3 How do I un-mount a partition ? Answer: Simply issue: - mount /u g: This will unmount drive g: if it's a Linux partition. ================================================ ================================================ Question 1.4: Mount says it's busy when I try to unmount a partition, what does that mean ? Answer: Unmounting can only take place if no files are still open and no other file system calls are taking place for that partition. Most likely you have an application running that accessed the partition at the moment you tried to unmount. You can immediately try again. ================================================ ************************************************ Section 2 Questions about problems using fsdext2 ************************************************ ================================================ Question 2.1: Fsdext reports my IDE as SCSI disks or my SCSI disks as IDE disks. Is this a bug ? Answer: I guess it is. I have not been able to determine what's causing it. Fsdext2 looks at a flag in the "Device Control Block" (a windows 95 kernel data structure) to determine if the drive is an IDE or an SCSI drive. My hunch is that some non- Microsoft device drivers do not set up this flag correctly. As far as I know, people can still use fsdext2, only the drive naming is incorrect. I'm afraid you'll have to live with it. ================================================ ================================================ Question 2.2: I have two IDE disks, both being the master on the two IDE controllers, so Linux names them: hda and hdc. However, fsdext2 lists them as hda and hdb. How can that happen? Answer: Right now, fsdext2 is not able to retrieve information about which controller an IDE disk is on. It just assigns names in the order the disks are administrated in the Windows 95 kernel. ================================================ ================================================ Question 2.3: When I look in a directory using the explorer or a dos box, I noticed that symbolic links are not supported. Is this true? Answer: No, symbolic links are supported. However, when enumerating directories, symbolic links are not followed. This is intentional as fsdext2 does not handle cyclic symbolic links properly. If these links were followed, recursively traversing all sub-directories might cause endless loops. ================================================ ================================================ Question 2.4: The explorer doesn't display the correct icon for my Linux partition. Is this a bug ? Answer: No it isn't. This behaviour was intentional. Just refresh the screen (press F5) to get the correct icon. ================================================ ************************************************ Section 3 Questions about exciting features for fsdext2 ************************************************ ================================================ Question 3.1: Is there also a read-write version of fsdext2 ? Answer: No. All my current implementations are a read-only version only. My latests plans/ideas on fsdext2 do not include a read-write version for Window 95. ================================================ ================================================ Question 3.2: Will fsdext2 work on windows NT ? Answer: No, file system drivers (FSDs) are not binary compatible between Windows 95 and Windows NT. However, as soon as I have the proper tools and documentation, I'll start working on an NT port. ================================================ ================================================ Question 3.3: When will the NT version be available ? Answer: As soon as I have the proper tools and documentation, I'll start working on an NT port. For that I need at least the IFS kit from Microsoft. Currently the kit cannot be shipped outside the US/Canade because of the export legislation on file encryption (the IFS kit seems to have some encryption examples in it). If some one out there has any thought/tips/hints or whatever on how I can get my hands on the IFS kit, I'll be happy to hear them. I think it will take me at about 6-12 months to get something working. I have attended OSR's NT's file system driver course so I know from the "fat guy with the pony tail" that this is _not_ going to be easy. ================================================ ************************************************ Section 4 Questions about the debug version of fsdext2 ************************************************ ================================================ Question 4.1: What's the use of the debug version of fsdext2 ? Answer: The debug version of fsdext2 generates a log file in which it stores sensible information (well, at least to me :-)) on what is has been doing. When you encounter a bug, you are encouraged to repeat the actions that lead to it under the debug version. Except for the log informatiom, the debug version is exactly the same as the release version. Don't forget to attach the log file in your e-mail back to me! ================================================ ================================================ Question 4.2: How do I install the debug version of fsdext2 ? Answer: 1. Install the non-debug first, then chdir to the debug directory and copy the .vxd to the \system directory. 2. Disable Windows' write behind cache in: My Computer->Properties->Performance->Filesystem-> Trouble Shouting 3. If vext2d is already loaded, reboot the machine. (Vext2d is already loaded if you have run mount.exe at least one time after logging on) ================================================ ================================================ Question 4.3: How do I use the debug version of fsdext2 ? Answer: The debug version will create a logfile (c:\\fsdext2.log) which you will not be able to put somewhere else. Also, when a file system is mounted, do not try to delete the log file if it is becoming too large. The .vxd always positions the file pointer at the last offset written. Deleting the file when the .vxd is running will only cause the beginning of the file to contain garbage. Try to minimise the file access (and hence the size of the log file) when repeating a crash test!! ================================================ ================================================ Question 4.4: can I finetune the kind of information being logged ? Answer: Yes. Mount allows you to view and dynamically change the kind of debug information being logged. You can use the /d option to see the current debug level. The '*' in the first colomn means that the specific level is enabled. Use /d=value to set a new level. "Value" is the sum of the individual debug levels you see in the /d output. Value may be: - a decimal number (10 or 3245 etc), - a hex value (0x12 or 0xff etc), - the string "def" for a default setting, - the string "all" for all settings Use "all" if win95 crashes, use "def" if you wonder why a certain application does not work the way you expected. ================================================ ------=_NextPart_000_0006_01BF937A.26DA5800--
