The original version of CiderPress used a WinHelp help file, built with an application called HelpMatic Pro. This app used a proprietary format, and had no facility for exporting to "raw" HPJ + RTF files, so I decompiled the HLP and imported it into HelpScribble. Using HelpScribble, I cleaned up the help file formatting a little, fixed up the table of contents, and exported as "raw" HtmlHelp (HHP, HHK, HHC, and a whole bunch of HTML). I also split the pop-up help text, which isn't supported by HelpScribble, into a separate text file that Microsoft's HTML Help Workshop understands. I'm checking in the files that HTML Help Workshop needs to generate a CHM, so anyone can update the help text. I'm also checking in the CHM file, rather than adding the help workshop to the build, so that it's not necessary to download and configure the help workshop to build CiderPress. This change adds all of the updated help, but only updates the Help and question mark button actions for one specific dialog. A subsequent change will update the rest of the dialogs. This change is essentially upgrading us from a totally obsolete help system to a nearly-obsolete help system, but the systems are similar enough to make this a useful half-step on the way to something else. The code will centralize help activation in a pair of functions in the main app class, so any future improvements should be more limited in scope. This also adds a build step to copy the CHM to the execution directory.

<P STYLE="margin-top:0;margin-bottom:0;"><FONT FACE="MS Sans Serif" SIZE="2">Disks can be opened as "logical" or "physical" volumes in Windows. Understanding the distinction is important. The basic difference is that a "logical" volume has a drive letter associated with it (e.g. "A:\" for your first floppy drive), while a "physical" volume is numbered (e.g. physical device 0 is your primary hard drive). From the operating system's perspective, a "physical" disk has a partition table in block 0 that describes one or more "logical" volumes. Floppy disks are an exception; for them, "logical" and "physical" are equivalent. A CF card reader may present itself to the system as a physical disk, in which case Windows will try to find a partition table in block 0.</FONT></P>

|
<P STYLE="margin-top:0;margin-bottom:0;"><FONT FACE="MS Sans Serif" SIZE="2">ProDOS and HFS volumes don't have a partition table in block 0, which can cause some confusion. In some cases you will see a "physical" volume for the CF card but no "logical" volume. In others the "logical" volume will appear and will be as large as the "physical" disk. If Windows thinks it has a valid partition table, the "logical" volume may be a small subset of the "physical" disk.</FONT></P>

<P STYLE="margin-top:0;margin-bottom:0;"><FONT FACE="MS Sans Serif" SIZE="2">The bottom line is that it's best to use "physical" disks whenever possible. However, it's not always possible. You can't treat a floppy drive as a "physical" disk in Windows 2000, and access to "physical" hard drives in Win9x/ME is tricky. You have to access floppies as "logical" volumes under Win2K, but if you do that under Win98 you will have terrible performance in some circumstances. It would be nice if CiderPress could automatically do the right thing in all cases, but every CF card reader is different, so CiderPress tries not to limit your options.</FONT></P>

<P STYLE="margin-top:0;margin-bottom:0;"><FONT FACE="MS Sans Serif" SIZE="2">CD-ROM drives have their own access method. No version of Windows makes it easy to read blocks from a CD-ROM with an unrecognized filesystem format. Under Win2K/XP, CiderPress relies on a technology called SPTI (SCSI Pass-Through Interface) to access the disc. Select the drive you want from the "logical" list, by letter (e.g. "D:\"). Under Win98/ME, it's necessary to use an ASPI driver (Advanced SCSI Programming Interface), just like CD recording applications do. CiderPress will look for "wnaspi32.dll", and use it if found (Win98 includes it -- look in the About box to see if it was loaded successfully). CD-ROM drives show up in the "physical" list, described by manufacturer and model number. Some external CD-ROM drives may not show up in the list.</FONT></P>

|
|
<P STYLE="margin-top:0;margin-bottom:0;"><FONT FACE="MS Sans Serif" SIZE="2">Generally speaking, SPTI and ASPI have equivalent performance. The only notable difference is that SPTI requires exclusive access to a device, so you can't have a CD-ROM open in the file list and then open it in the volume copier. Some ASPI layers will pick up devices other than CD-ROM drives, such as SCSI hard drives, Zip drives, and even CF card readers.</FONT></P>

<P STYLE="margin-top:0;margin-bottom:0;"><FONT FACE="MS Sans Serif" SIZE="2">Hard drives partitioned for an Apple II or Macintosh can be accessed if attached to an IDE or SCSI connector. Under Win9x/ME you can only access drives that the ASPI layer can find, which usually means you can only get to SCSI hard drives.</FONT></P>
