how do you install win95 from dos prompt when The cd drive M: is not reconised
 
What drive is your CD mapped to? Check the mscdex instruction in your autoexec.bat. The letter that comes after /L: is the drive you have mapped it to. If there is no /L: then it is mapped to the next drive available, probably D if C is the only drive in the system.
 
Reboot in DOS and watch the screen. During config.sys it should show the CD being found and during autoexec.bat it should show the drive letter being assigned.

I suspect that you may be having a problem with the DOS as CD support wasn't built automatically until 98. Try downloading the 98SE version bootdisk from and use it for CD support. There will be no problems using it just for that purpose.

The known Drive Is M: but still not showing in DOS tried to load disk in M: CD Drive but to no avail is there any other method. Cannot even get to Bios Even to change anything keeps booting to A: Drive all the time
Answers welcome thanks Data1
 
If you don't already have it, try adding:-

LASTDRIVE=Z

in the CONFIG.SYS file.

Did you carefully watch your screen as Ed Fair suggested? This will give you vital info on what is happening when the drivers are loaded. A failure will produce an error message.

The POST screen usually lists all main devices found. Does it show hard disk, CD-ROM, as well as the floppy, etc etc?

You could also change the known drive to something less than M:. DOS , if I recall correctly, only provices for 3 drive letters beyond what it finds as active partitions. So if it is booting and finding C: anything beyond F: wouldn't exist.
I've generally let DOS sort it out for itself by leaving drive assignment off autoexec.bat When you get the OS up and running you can assign things to sit where you need them.
There are reasons to assign them at the beginning, but nothing that can't be handled later.
