Hello I have a 486 with 8megs of ram and a 540 mb hard drive. I was installing a new floopy drive. I disconnected the hard drive and then went to bed because I didn't have time to finish. Well in the morning I finished and inserted the hard drive and connecting the cable to the controller. Everything was and is in place. Known When I turn my computer on it said "Missing operating system ". So I said ok. I will insert a bootdisk and start over. With inserting a bootdisk of dos 6.0 and restarted the computer I didn't get anything. Justa a cursor. I took out the bootdisk and restarted and still got a cursor. So I thought that the problem may have been the floppy drive that I installed, I replaced it with the old one and still just a cursor. Please someone help me. mike

ive never installed dos 6.0 but i have installed 6.22 and i dont think any version of dos has a cursor on the installation until you get to win 95 or 98. i may be wrong though. id try a different boot disk.

Mike, Is this a total new install of DOS or just the installation of the floppy drive? If the new floppy drive is a different type than the old one-for example you took out a 1.2 Meg 5-1/4" floppy drive and replaced it with a 3.5" 1.44 Meg floppy drive, you will need to go into the BIOS and make sure the new drive is recognized there. If DOS 6.0 is downloaded from the Internet you could be using a disk with no system files on it. If you want to try another DOS system (its compatible with MS-DOS), download DR-DOS 7.03 from here and create the 5 install disks. ftp://ftp.lineo.com/pub/drdos/DR-DOS.703/images/ Download these 6 files into a temporary directory; DISK01.144 through DISK05.144 & mkdskzip.exe Double click mkdskzip.exe and it will expand into a number of files. One of the files is Makedisk.exe. Double click it and it will lead through making the 5 floppy disks. Boot up to disk 1 and the installation will begin.

most likely you have a cable attached backwards. Check very carefully and make sure that pin one, usually the red line on the cable is alighned with pin one on the motherboard. also to pin one on your HD and Floopy Drive.

You installed a floppy drive and then neither the hard drove nor the floppy drive would boot? Two cables on backward? Bad controller? That is what to check. The red line goes to pin 1. If you look long enough at most controllers or drives you will find pin one maked. Not marked well but there will be a 1 somewhere to give you a clue. The marking on the ribbon cables goes to pin one. Also pin 1 is often near the power connector at drives.
