I may try to move the Reno to an Adaptec card which hold >my SCSI-2 HD and see what happened. 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. >This is the second major OS that MediaVision don't support ... first >one was OS/2 Warp ... both sound card and SCSI adapter not supported. Warp's hardware support is not wonderful. Better than OS/2 2.1, but still poor. >The funny thing was that I install WIndows 95 using the CD ... it >manage to copies all files and finished installation from it but after >a reboot, my CD no longer there. Attempts to add it back using Add >hardware feature also proves futile. Sounds definitely as though Win95 does support your CD-ROM as a generic SCSI CD-ROM. >> >> Second, I cannot set the applzone higher than 2048 while running E/D in a DO >S >> window.

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. >> Lastly, whenever E/D crashes with a GPF in a DOS window, I cannot restart >> Executor at all, either from the DOS prompt or when I close the window and >> try restarting Executor.

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: http://pclt.cis.yale.edu/pclt/opsys/default.htm It is well worth reading, and is where I learned the above from.
