DOS6.22 problem

Ah, on a PC now...

By default. CONFIG.SYS does not have a PATH command (unless you're using OS/2) so you will have to use the full pathname of the device driver, for example
C:\DOS\EMM386.EXE
C:\DOS\NOSMOKE.EXE
C:\DOS\HIMEM.SYS

The PATH= command resides within the AUTOEXEC.BAT file, and this tells DOS in which directories to look for files if it is not present in the root
So, for example, you will have (when doing a DIR)
C:\DOS
C:\MENU
C:\MYPROG
C:\ACAD

and the PATH then will be
PATH=C:\DOS;C:\MENU

Thus DOS knows it will need to look into the DOS and MENU directories if any program is called, before returning with a Bad Command or File Name error.

But I digress

When networking with DOS, the LASTDRIVE=Z: need to be added to the CONFIG.SYS file (usually the last entry) before the NDIS (or network) drivers

Any chance of getting the contents of the original CONFIG.SYS and AUTOEXEC.BAT off from the original hard drive, even if it means slaving that drive into the CNC PC?
Thanks for the examples.

Last time I did dos was at Columbia Computers on the foreshore in 1992!

Got all the stuff in the right dir but I need to change the path to cnc1

But when I do this via the net.exe command I get a " out of memory" error.

We had a IT guy come in to fix the hdd. He cloned the drive first but could not use it because something went wrong with the fat16 / NTFS so he could not recover any thing.
So all the old settings are lost

Eish Spiff, I feel your pain.
Luckly our old CNC machines does not use network drives :)

Believe me when I say that upgrading the OS or hardware is not always that easy.
Some of these machines have custom hardware or interfaces that does not work on anything else!!!

We still have machines here that uses 1.44 stiffies!!
Took me a couple of years and lots of work to find a working usb solution.

Then I still have a couple of Digital Vax machines running VMS :)
Some of them have been running 3 years without a restart!!

If you are still stuck, look at a 'fresh' copy of Quarterdeck QEMM386. It was solving many problems with high memory with network dirvers when EMM386 couldn't cope. It seems Wikipedia points to download page for free (I paid for it).

Or, go for OS/2... You really can have 640k of RAM in your DOS session....

thanks - yes I had the same problem with stiffies!! I bought a usb stiffie drive as our pc's don't have stiffie drives anymore, but I'm running out of usable stiffies! lucky for me I found the MBB user "SERIOUS" who worked miracles on our smaller cnc machine and got it sorted and it's still running perfectly. even got the network working - no more RS232 :)

not going to go down the "upgrade os" route. learnt my lesson with my quadcopter - loading open source firmware can be costly!!

thanks guys but for some reason I cannot get enough memory to edit the net.exe file in order to change the network path.

Another alternative - setup multiple copies of config.sys and autoexec.bat

1x set for network drivers to copy files over
1x set without network drivers, to maximize memory for the software you want to use

so at reboot/startup it will ask you which set of autoexec/config you want to load, default will be without network drivers...

Still more DOS machines out there than Apple Macs. :p

Haven't touched DOS in twenty years...

I loaded MS-Dos 6.22 and Windows 3.11 on my old Asus eeepc 701 SD netbook yesterday. Haven't played with sound or network yet. Was just curious to see if it will run and it brings back many memories.
Still found myself sitting, thinking and trying to remember all I learned growing up with Dos years ago. It comes back, bit my bit.

Going to use my old netbook for old Windows 3.11 games and Dos games. I loved the games from way back then

the machines software was written for DOS6.22 - so loading any other OS will not work.

I'm certain that if OP could upgrade he would.

It's quite common that there are older CNC machines and the like that have to be controlled by incredibly old software.

Oh okey sorry I missed that part I thought it was just a network.

Did not know he is using mining and drilling machines, yea your fcked hehe
