    initial v1  
    11Hm, tried vfdisk.sys. If I add it after FAT32/HPFS/JFS, everything is working. But if I add it to config.sys before all IFS-es, vfdisk.sys mounts on U: drive letter (though, I specified it x:). U: is CDROM drive letter in my system. Then when fat32.ifs tries to mount on this U: drive letter, I got a trap in fat32.ifs somewhere in FS_MOUNT. Need to determine, where exactly. But I see that some pointer is NULL and it tries to dereference it. Also I see that when vfdisk.sys is loaded after fat32.ifs, VFDSIK floppy is mounted with in-kernel fat driver. Trying to remount this drive letter with remount.exe from ext2-os2.ifs, I see that fat32.ifs doesn't mount it, though it recognises all other FAT drives, including physical floppy, and even a CDRW disk with FAT filesystem. Why it is not mounted? Is it the usual .add driver, or what principle it is based on?

    3 So, looking at the logs, I see that on your machine, vfdisk.sys prevents fat32.ifs (and other drives IFS-es) to mount and it is initted ok indeed. But I cannot reproduce that on my machine, yet. Also, I don't understand what it does with /largefiles ? So, if I correctly understood, everything is working on your machine, if you disable vfdisk.sys? Disk access works? And CHKDSK works, but you got a trap in CHKDSK?
