Most people that want to get both their Windows and OS/2 versions of PMMail running from the same data set will need to do one of two things. Either make sure their data is on a FAT partition, or, if they have NT 4.0, add the HPFS support for NT. To do this, you need only to do the following: (NOTE: Registry hacking is a "do at your own risk" operation. Blueprint Software Works assumes no liability for this suggestion)

We should also note that the use of PINBALL.SYS on a Windows NT system is limited to 4 GB partitions. Support for HPFS using these settings will likely cause instability in your NT installation beyond 4 GB partitions.

1. Copy PINBALL.SYS from an existing Windows NT 3.51 installation (or the NT 3.51 install CD) into your Drivers directory.
2. Go into the registry editor (REGEDIT) and add a Pinball key to
   HKLMSYSTEMControlSet001Services (when Services is highlighted, select Edit -> Add Key).
3. Click onthis new key and add the following values:
   • ErrorControl = REG_DWORD: 0x1
   • Group = REG_SZ: Boot file system
   • Start = REG_DWORD: 0x1
   • Type = REG_DWORD: 0x2
4. Close the Registry Editor and reboot your system!

Alternatively, we have learned of a program which has all of the files you need and automatically changes your registry to properly give you HPFS support under Windows NT. The file is called HPFS_NT4.zip, available on the OS/2 BBS www.ostbbs.com
