Burning a CD-ROM

Question:

How can I burn a CDROM of Kurzweil data for loading into my K2?

Answer:

If you want to burn your own CD-ROM for your Kurzweil, you will need to be aware of the following information:

For K2000 Series Models with version 3.87, or K2500 Series Models with version 2.88B (Non-KDFX) or 4.21B (KDFX) or later, or any K2600/2661 Series

These versions add support for ISO 9660, making it extremely easy to burn a CD-ROM. You should consult your CD-Writer software for instructions on how to burn a CD-ROM in ISO-9660 format. Of course, your computer will need to be able to read the disk that contains the data you want to burn on to the CD-ROM. There are a few rules you should be aware of for burning an ISO-9660 disk.

ISO9660 support key points:

  • The Kurzweil OS supports CD-ROM XA (Mode 2) as well as CD-ROM (Mode 1)
  • The Kurzweil OS supports multi-session CD's, but some older CD-ROM drives may not support multi-session. In this case you will only see the first session.
  • File naming conventions that work: ISO-9660 level 1, MS DOS, and Joliet.
  • Do not select "use Macintosh extensions" when making ISO-9660 CD's.
  • Do not select "append version numbers" when making ISO-9660 CD's.
  • The maximum "path-length" (total file name, including directory names and slashes) is 63 characters, which means that files in highly nested directories may not be loadable.
  • Unicode characters do not display correctly.

For All K2000 and K2500 Series Models with older OS versions

These older versions don't support the ISO-9660 format, which is often used by computers. So to burn a CD, you must make a disk image copy of the DOS or Kurzweil formatted source disk that has your files. In essence, you will need to have another drive which is used as "staging" drive. By making a disk image copy, you copy sector by sector the exact format and data on the staging drive.

There are a couple of issues to be aware of. First of all, if you have a drive on which you have been constantly loading files, editing them, and resaving them back to the disk, you are likely to have a fair amount of disk fragmentation. Although not necessarily essential, it is recommended that the staging drive be defragmented. If the disk is currently in DOS format (instead of being formatted by the Kurzweil), you can use disk utilities program to defragment the disk. If the disk is in Kurzweil format, or you don't have a disk utility program, then the solution is to use the Kurzweil to backup all the data to another drive, reformat your staging drive, then restore the data to the staging drive using the Backup or Copy functions.

The second issue concerns drive size. If your staging drive is less than the maximum size of a CD-ROM (650 Mb), then you can simply make the disk image copy. But if the staging drive is larger than 650 Mb, then you need to be able to only copy a certain portion of the staging drive. In this case, defragmenting the drive is absolutely essential. Since a disk image copy simply copies data sector by sector, without regard to what is in those sectors, all of the data for your CD must be contained within the first 650 Mb of sectors on the disk. Also, your CD-ROM burning software will need to have the ability to copy only a specified part of the staging drive when doing a disk image copy. You will want to consult your CD-ROM burning software to find out how to burn a disk image copy.

K2x00 CD-ROM Image Maker is a freeware program for the PC, created by Bernard Perbal, which allows you to create a disk image file.
