- Try telling Win95 that it's a generic SCSI CD-ROM. Under Linux, all
- SCSI CD-ROMs are supported for data, since they all work the same way.
- You may find that audio won't work, but data will.

- Warp's hardware support is not wonderful. Better than OS/2 2.1, but
- still poor.

-
- Sounds definitely as though Win95 does support your CD-ROM as a
- generic SCSI CD-ROM.

- You are confusing conventional memory with extended memory. DOS is
- telling you that it has 606kb of free conventional (ie below 1Mb)
- memory. -applzone tells executor to allocate that much extended
- memory for its use. Without that switch, my guess is that it tries
- to use conventional memory only and doesn't like it.

- As I said, that's probably Win95 getting confused. Because of the
- way Win95 uses DOS virtual machines, and lets them directly access
- the hardware, the DOS program can still crash the entire system.
- Under OS/2 this is less likely, because OS/2 does not allow this sort
- of system access. Win95 emulates MS-DOS, whereas OS/2 emulates the
- entire PC, including all the hardware (which is why you can boot any
- MS-DOS version or other PC operating system that doesn't use protected
- mode, such as DR-DOS, in a window under OS/2. You can't do that under Win95).
-
- There is a very good summary document of the differences in
- technology and advantages/disadvantages of DOS, Windows, Windows for
- Workgroups, Windows 95, Windows NT and OS/2 available on the web from:

- It is well worth reading, and is where I learned the above from.
