There is probably a bios string showing up on your first screen as you boot the computer.
If you supply the bios string, we may be able to find info about and possibly a manual for your retail mboard model.
It's likely the bios version is that for a retail mboard model rather than a brand name system bios version.

If that's the company that built your computer, they have no apparent support on their web site for their older models
You could try contacting them.
1990 overall AMI bios version (a / in the zero)
- your computer was made no earlier than 1990.
Bios is showing....
Floppy drive A : 720 kb floppy disk
ROM bios date: xx/xx/91
- it has a 1991 model specific bios version. The computer was probably made in 1991, unless you or someone else flashed the bios with a newer version .
Base memory size: 640 kb
Ext memory size: 2424 kb ?
- you have 3 mb (3,096 kb) of ram installed ?
Hard disk C: None
Hard disk D: None
- at the time the computer was made, 720 kb drives were a lot cheaper than 1.44 mb drives, and the bios defaults were often set to a 720 kb drive.
Some people never installed a 1.44 mb drive. It may or may not have come with the computer.
You may have a 720 kb drive or a 1.44 mb drive. It's hard to tell the difference by looking at it in most cases, and if so which one it is can be confirmed by searching the web with it's model or part number,
or - when you prop up the flap when there is no disk in the drive, a 720 kb drive has one tiny sensor switch "plunger" sticking up on one side for the one rectangular hole in the 720 kb floppy disk, a 1.44 mb drive has two of them, one on each side.
A 1.44mb drive can read both 720 kb and 1.44mb floppy disks, but a 720 kb drive cannot read 1.44 mb floppy disks.
If you have a 1.44 mb floppy drive you must specify that in the bios Setup.
Win 95 boot disk is 1.44 kb - it has the two rectangular holes - 720 kb floppy disks have one.
It cannot be read in a 720 kb drive, or in a 1.44 mb drive if the bios is set to a 720 kb drive.
"There's a good chance your 486 has an 'auto detect hard drive' option on the first or second bios setup page"
Standard setup screen
shows User type
Hard Disk Utility selection - that may be equivalent to Auto hard drive detection in newer bios versions.
Date Jan 2 1980 - the default date is probably Jan 1 1980
Your Cmos battery is dead or too weak or is not getting a good connection or it's polarity is backwards (installed upside down in it's socket, or if it's connected by wires, the connector is on the pins backwards).
If your mboard has a flat "coin" sytle battery, they generally last about 5 years.
Cmos batteries for desktop computers are nearly always not rechargable.
- it appears your bios version set to default settings does NOT auto detect drive parameters like newer bios versions can.
- select a drive type that matches the parameters your hard drive has
- if no drive type matches the parame ters your hard drive has, select the User type and type in the parameters
- or - if you choose Hard Disk Utlity, that MAY be able to auto detect the drive parameters , or not. If it does detect them, you need to Save bios settings.
Old bioses often cannot detect or support hard drives larger than 528 mb (binary size). If you haven't changed the hard drive(s) to a larger size that wouldn't be a ptoblem.
Your hard drive(s) size(s) may not meet the minimum requirements for Win 95
