OK now that i have a real copy of ms-dos on my old pc. I need to set up the drivers for the USB flash drive and the CD ROM. i have the drivers on the F: drive. I need help with the Autoexec.bat file and the config.sys file. i have read the Q&A on autoexec. and config. files. but im am still not sure about how to realy set them up ther are some exsampels that mostly show with windows, i dont have windows on it. So im left with some other quistons. like how meny devices can i use? is ther an order i need to make sure the dvices are LISTED.

Packard bell model #P160119601, the motherboard is Agna-6wmm7, it uses PC-100 ram 64 megs, hard drive is a WD Caviar 84AA (set with 4 partions C: D: E: F: all portions or about 2gig in size), The OS is  MS-DOS 6.22.  It has a floppy 3.5 and a DVD ROM.

Thank you for any help one can send my way.Just a thought sence the drives im trying to set up are not external, i should not have to change my autoexec.com. just the config.sys. if im right on that?    I'm not sure about the flash drives, but you can find a driver for CD-ROM/DVD-ROM drives here:


ftp://ftp.ehu.es/cidirb/2000/speedsys/oakcdrom.sys


This is the Driver I usually use when running DOS or windows 3.1.

you'll need to modify both config.sys and autoexec.bat.


config.sys. add this after DEVICE=HIMEM.SYS:
Code: [Select]DEVICEHIGH=C:\DOS\OAKCDROM.SYS /D:OAKCD

autoexec.bat- plop this line at the bottom:

Code: [Select]MSCDEX /D:OAKCD
(obviously I am assuming OAKCDROM.SYS was placed in the DOS directory).



Flash drives, I'm afraid, I've never used successfully via DOS.
this did not work i droped the code where you asked and this is the code i put in
  Code: [Select]DEVICEHIGH=F:\OAKCDROM.SYS /G:OAKCD
the driver is on my f: drive and i want to make the cdrom drive G:

i also added this to my autoexec.bat
Code: [Select]MSCDEX /G:OAKCD
But i am thinking that it is my config sys that is not right. Here is what it looks like after i add the code
Code: [Select]DEVICE=C:\DOS\SETVER.EXE
DEVICE=C:\DOS\HIMEM.SYS
DEVICEHIGH=F:\OAKCDROM.SYS /G:OAKCD
DOS=HIGH
COUNTRY=044,,C:\DOS\COUNTRY.SYS
DEVICE=C:\DOS\DISPLAY.SYS CON=(EGA,,1)
FILES=30
Now i have seen some other code with a umd after the dos=high  ok i am realy starting to fell dum now. i wen back and checked my config.sys and the reason it did not work is that i had missed spelled DEVICEHIGH i had spelled it DEVISEHIGH.

So now that i have fixed that. The driver is loading but i get
"Illegal option 'g'
usage: MSCDEX [/E/K/S/V] [/D:driver> ... ] [/L:] [/M:]"

any thoughts? becouse i found this post on a defrent site i will just post the content as a quote Quote

I finally got it to work!! I have the following files on my boot disk:

himem.sys
ramrd.sys
usbaspi.sys
di1000dd.sys

And my config.sys is as follows:

dos=high, umb
lastdrive=z
device=himem.sys
device=ramfd.sys
devicehigh=usbaspi.sys /w /v
devicehigh=di1000dd.sys /dG

The file just above assigns my PNY 128MB thumb drive to the G: drive, and I can then access it through DOS. I don't have anything in my autoexec.bat file (don't really need it since I'm not accessing an external cd-rom.

Thank you that helped alot. i now have a working cd rom still working on the usb though.  when i do ge the usb up and running i will be sure to post it here.
