I have two problems with command.com on my ATT 6300 running
MS-DOS v2.11.
First, I want to have command.com load from my C: drive instead
of A:. I have tried putting the line:
SHELL=C:\COMMAND.COM /E:512 /P
in my config.sys file. I also put the line:
SET COMSPEC=C:\COMMAND.COM
in my autoexec.bat file. However, all that does is give me an
error message "Command search directory not found", or something
like that, when I reboot.
Second, I would really like to increase my environment space so I
can set a reasonable PATH variable. Has anyone else tried this?

Forgive the cross-posting, but I've seen a similar question from a PCjr user ont comp.sys.ibm.pc and hopefully this will answer both.

Yes, it appears you are missing a parameter to the SHELL= line in config.sys. You need to add C:\ to the line to tell command.com where to look when it needs to reload tiself from disk. In your case, the chrrect line from config.sys should be: SHELL=C:\COMMAND.COM C:\ /P or even SHELL=A:\COMMAND.COM C:\ /P since you are booting from A:. BTW, Is C: a hard disk or a ramdisk? It would seem to me that if it were a ramdisk, you couldn't set the SHELL in config.sys since there wouldn't be a copy of command.com in C:\ yet. On the other hand, it C: is an HD, why boot from A:? Note on COMSPEC under MS-DOS 2.x- There is a bug in DOS 2.x which often clobbers the COMSPEC variable. This will cause DOS to ask for a valid command.com in drive A:, even though you have set COMSPEC=C:\COMMAND.COM in your autoexec.bat. PC Tech Journal (and others) have developed programs to get around this problem. Try checking local BBS's for a program called (I think) COMFIX. > Second, I would really like to increase my environment space so I > can set a reasonable PATH variable. Has anyone else tried this? Yes, but if you're running 2.11, you can't do it the way you are trying to. The /E parameter to command.com was not added until DOS 3.1. For DOS 2.x, you need to patch command.com (sorry I don't have the address handy) or use one of the programs which dynamically expands the environment size. (Someone posted a program named ENVSIZE.COM a few months back.) Hopefully, this is of some help. -- Name: John Ruschmeyer US Mail: Monmouth College, W.

Yanagida >Seattle Silicon >3075 112th Ave NE >Bellevue, WA 98004 >(206)-828-4422 I must not know the whole story because it is easy to boot from the C (hard disk) drive on the AT&T PC-6300. You must first format your hard disk with the /s option in order to copy the two MS-DOS hidden files on to the hard disk. This will also copy the command.com file into the root directory. Now boot without a disk in drive A and the computer will boot from drive C. The only reason I can see for using the SHELL= option is if you put your command.com file into a different directory, such as \bin. You would then need to put the following line in you config.sys file. Shell=\bin\command.com or SHELL=c:\bin\command.com NOTE: If you also load you MS-DOS utilities into \bin, you will need to set your PATH environment.

I have tried putting the line: > > SHELL=C:\COMMAND.COM /E:512 /P [ More stuff] Uhhhh! Why don't you just leave the a: drive empty? The machine should then boot off of the c: drive if it's ready and command.com will be acquired off of that drive. -- John Cornelius (...!sdcsvax!piaget!jc)
