Hi, I'm glad that I can help a bit! 😀
Your BIOS Setup is dated 1992.. Maybe it predates the more common LBA (28-Bit) that was introduced in 1994.
From what I found out, the original LBA was 22-Bit and an optional part of Western Digital's EIDE specifications from 1990.
According to this site, some BIOS from before may 1996 can have issues with drives larger 2GB.
Here's another Vogons thread that mentioned 22-Bit LBA:

I'm sorry to say that I can't be more precisely. 🙁
As a workaround, you can try using a Dynamic Drive Overlay (DDO), like EZ-Drive.
Or use XT IDE Universal BIOS. Many people use an old network card as a host for their ROM chip.
If nothing works, I can send you a snail mail with a copy on an old EPROM also.
Edit: Please don't let yourself getting confused by all these numbers, they are just.. numbers.
Way back in the 1980s people already used fake parameters, because the BIOSes had hard-coded values.
Essentially, all that matters is staying within the maximum capacity.
So people were using, say, an 80MB IDE drive as a 40MB IDE drive - until they upgraded.
Initially, ca mid-late 80s, it was required to make sure that all the individual parameters were equal or lesser: Cylinders, Heads, Sectors (CHS).
Because, HDDs still worked with physical (or real) values.
Anyway, by the turn of the decade (80s/90s) most HDDs started to use some sort of translation, not E-CHS/Large or LBA really, just a simple translation to decouple addressing from the physical drive mechanics.
That's when things got both more simple and more complex. 😉
Edit : Just one warning - please never use the Low-Level Formatting in the BIOS Setup.
It has the ability to confuse flash media, even!
FORMAT, FDISK etc are all harmless, though, no worries.
