Formatting a Win 98 HD to DOS 5.0. (Need HD for a 486)

May 8, 2012 at 11:50:38
Specs: win 98 , pent III
Using a pent iii machine, the A:drive with dos 5.0 can't see the C:drive. I need to format the hard drive with 5.0 so I can use it in a 486 computer. This hard drive has win 98 operating system on it. Is there a utility out there to help me. Ive tried Sys C: from the A drive, and it says incorrect dos version. theres got to be some kind of utility out there.

I need to run a 486 for a coil winding machine that runs 8088 to 80x86 arhitecture. I prefer to have a hard drive in the 486 although it runs fine using floppies. the coil winder uses the printer port and won't work on anything higher than 80486 because of the Basic code program,

First, does drive correctly show in bios?

Then what does fdisk show.

All the rest may or may not be true. Basic can run on anything.

Hang up and live.

Why not use the MS-DOS 7.xx which is the W98 sub-system ?

Unless the software specifically needs for MS-DOS 5, there is no need not to MS-DOS 7.xx

Googling is quicker than waiting for an answer....

If you must use DOS 5, you first need to find out:

1. Will the 486 that you're going to use recognize the drive's size? Many older machines won't recognize anything greater that 540MB; some may recognize larger, but it depends on the BIOS. Would be better if you could post the specs of the 486 you're trying to get going.

2. If you're capable of recognizing a larger drive, you'll have to partition the drive off into 2.1GB partitions---the largest partition that MS-DOS's file allocation table can recognize. The largest hard drive it can recognize is 8.4GB.

Hi Spin,

I would use dos 6.2n as it is better than version 5.

It could be the disk has been previously formatted (fat32 or ntfs) such that it cannot be 'seen' by dos.

FDISK will need to be run to determine (and maybe change) partitions etc.

Partitioning and/or formatting the hard disk will wipe everything on it.

Advise make and model of hard disk. If it is too big for dos, generally the disk maker has a disk manager program that can be downloaded to overcome this aspect.

Please advise back on progress.

Good luck - Keep us posted.

I downloaded DOS 7.1 and was able to boot the pent III from a:drive. Tried to format hard drive (20 gig).... says unable to "format network drive".... Ok, I searched a bunch of stuff on that and had to FDISK a partition on this hard drive. Finally able to succsessfully format the C:drive with 7.1. Took this 20 gig hard drive out and placed it in the 486. Booted to the A drive with 7.1 successfully. Tried to set the hard drive up on the 486 in the bios as there isn't an auto detection in the 486. Still can't see the hard drive in the 486. It probably has something to do with the size of the hard drive. I surfed somemore and found out there may be DISK MANAGER software that might allow setting up a large hard drive on this 486. The broken hard drive in the 486 is a ST3243A (214 MB). I may buy a replacement if I can't get this large hard drive set up. What jumper selections should this hard drive be set to? master, slave, or cable select? is there any free disk manager software that might work?

I uploaded this awhile back:

If I recall correctly you ID the drive as type 1 in cmos/bios setup, then boot with the diskmanager disk

If you don't want to screw around with driverguide I can try to find the file on my drive and email it.

You'll probably want to set the drive as Master or if it's a WD drive and the only drive on that cable, set it to Single, which is usually 'no jumper'.

Edit Who made the 20 gig drive--Seagate, WD, etc? I might be able to locate something more specific for that drive.

Hi Spin,

strap the drive to master (or master with no slave if that option is given) and use on your primary ide interface cable.

I think 20 gig is just not going to work on your dos machine as it is too large. There is a size limit even when disk manager programs are used.

As a matter of interest, where are you based? I am in Hammersmith, West London.

Good Luck - keep us posted.
