It's kind of hard to give you more specific information since you
haven't provided much information, but I'll do what I can.

I assume you normally enter the BIOS of the system by pressing
F1, F2, F10, Escape, or Delete while the system POSTs.  It was
common for some systems to include the "BIOS" setup application
on a special partition of the hard disk drive.  I know that
older Tandy and Compaq systems had this "feature".  It just may
be that partition is damaged, so you can't access your BIOS or
boot the hard disk, but your data may be fine.

It's also possible, and somewhat more likely that the hard disk
in the system died completely.  This would be complicated further
if the system setup code is stored on the hard disk itself.

Assuming that IS NOT the case, I would recommend that you
download a good MS-DOS boot disk.  Get an MS-DOS 3.3 boot disks:
<http://www.oldstuff.myagora.net/powerload/bootdisk/msd330bd.zip>
on another machine and write it to a disk using WinImage on
Windows, "dd" on UNIX, or "Disk Copy Plus" for MS-DOS.

If the system can boot that disk, you should check and see if
you can access your hard disk, by entering "C:".  If so, a
simple "SYS C:" may make the disk bootable with DOS 3.3 again.
If not, see if "fdisk" utility reports a drive present.  If
not, you probably need to replace the drive.  If it's there
but corrupted or has no partitions on it, you'll have to
recreate the partition or partitions, format, and reinstall DOS.

For a 486, I'd recommend using a later MS-DOS version. You have
some great choices now, including DR-DOS, PC-DOS, PTS-DOS,
ROM-DOS, FreeDOS, MS-DOS 6.22 or MS-DOS "7.10" which was the
updated DOS included with Windows 98SE.  I can assist you with
installing an up-to-date DOS release possible if you find that
course of action necessary.

Let us know what kind of drives you have in your system.  Do you
have a 3.5" or 5.25" floppy drive?  Do you have ISA, EISA, VLB,
or maybe a PCI bus in your system? Know the date it was made?
What kind of hard disks and controller is in the box?  Everything
should work easily for MFM, RLL, and IDE disks, but SCSI systems
may need special drivers to work fully.

Hope you can boot a floppy and find your data OK.
