You could try reseting the CMOS configuration - there's a jumper alongside the SIMM sockets to do this.

You could try going into setup and changing the com port address, although I do believe that clearing the CMOS will force the system to automatically reconfigure itself at the next power on.
The system should recognise a 10Gb disk with no problem, once you're using the latest version of the BIOS - I put a WD200 (20gb) in mine last night. How much of the disk capacity does it show?

True! Some BIOS images are not containing specs for large size Disks. A BIOS update would normally solve such kind of problem.
However, there is a question which was not raised yet. Namely, how many partitions have you set on your new HD? Could also be that only C: is correctly identified, with the DCROM moved to another letter than D: and partitions at E: or F:...Ect are missed.
Should that case occur, the solution might lie with resetting the Disks boot-sequence in the BIOS Config.

When you install the Rompaq, it actually copies itself to the BIOS "ROM" (which is some sort of EEPROM or flash memory) on the system board.
Because you created the first partition on the disk BEFORE upgrading the BIOS you probably need to use fdisk to remove ALL the partitions from the disk and then reinstall to get the full disk capacity.

I've often experienced that one partition is the best option starting with a new HD. Questionably, this would help that the whole disk-capacity is recognised by the BIOS more easily. Additional partitions can be further on created with utilities such as "Magic Partion" or "Partition It" for example.
This said the BIOS remains the control-tower for the system. In your case, I mean it must contain a ROM image which allows for the correct identification of large-size disks. So you may be whishing to check that this function is referred to in your ROM update specs at the first hand.
May be I am wrong, but I believe that F10 is the Compaq/HP preferred key for getting into the BIOS settings at start up. Also that this command is exclusively dependent on the BIOS model itself. Conversely, it seems that recent HP BIOS versions are utilising F1.
To summarise this, try to fdisk again with one partition only, then format, install the OS and tell us what happens (don't forget to create or get a boot-disk on a floppy at the first hand).

Understand your confusion since old models would require that setup/F10 be put on the disk (can be downloaded from HP/Compaq site), wheras new models had this function integrated into the BIOS.
I am afraid this variety is much specific to the manufacturer.

Compaq has almost always done things differently from the other manufacturers and has also, over the years, changed how they do things. Whilst this can be confusing, it also allows them to be innovative and in many cases to offer features that their competitors don't.
Let me explain the specifics of the Deskpro2000 5166, since that's what you're working with.
This is an old machine, and when it was released Compaq was using a system partition on the disk to store CMOS setup utilities and hardware diagnostics.
Although you may have read elsewhere on this forum that the BIOS resides on the hard disk, that is incorrect.
On a Deskpro2000 5166 the BIOS is stored in flash memory on the system board - look in between the riser card slot and the powersupply connectors for a small square IC. Because this is flash memory, you can upgrade the BIOS by downloading a ROMPaq that copies itself to this chip. When executed the ROMPaq unpacks itself to a bootable floppy that you put in the A drive, power on the system and follow the prompts - I'm mentioning this so that you understand the system doesn't need a hard disk or the CMOS setup utilities & diagnostics to do this BIOS upgrade.
When installing a new disk, larger than 8.4Gb, the correct process would be to upgrade the BIOS using the SP15800 ROMPaq and then to install the new disk and load the CMOS utilities & diagnostics from the SP4711 SoftPaq and finally to install your operating system.
Over the years I have maintained several different models of Deskpro and have successfully installed 20Gb disks in a number of Deskpro2000 5166 systems using the steps outlined above. I've also done this with 5166MMX systems, but of course using different ROMPaq & SoftPaq numbers.

CMOS - Abbreviation of complementary metal oxide semiconductor. Pronounced see-moss, CMOS is a widely used type of semiconductor. CMOS semiconductors use both NMOS (negative polarity) and PMOS (positive polarity) circuits. Since only one of the circuit types is on at any given time, CMOS chips require less power than chips using just one type of transistor. This makes them particularly attractive for use in battery-powered devices, such as portable computers. Personal computers also contain a small amount of battery-powered CMOS memory to hold the date, time, and system setup parameters.
BIOS - Pronounced "bye-ose," an acronym for basic input/output system. The BIOS is built-in software that determines what a computer can do without accessing programs from a disk. On PCs, the BIOS contains all the code required to control the keyboard, display screen, disk drives, serial communications, and a number of miscellaneous functions.
The BIOS is typically placed in a ROM chip that comes with the computer (it is often called a ROM BIOS). This ensures that the BIOS will always be available and will not be damaged by disk failures. It also makes it possible for a computer to boot itself. Because RAM is faster than ROM, though, many computer manufacturers design systems so that the BIOS is copied from ROM to RAM each time the computer is booted. This is known as shadowing.
Many modern PCs have a flash BIOS, which means that the BIOS has been recorded on a flash memory chip, which can be updated if necessary.
The PC BIOS is fairly standardized, so all PCs are similar at this level (although there are different BIOS versions). Additional DOS functions are usually added through software modules. This means you can upgrade to a newer version of DOS without changing the BIOS.
PC BIOSes that can handle Plug-and-Play (PnP) devices are known as PnP BIOSes, or PnP-aware BIOSes. These BIOSes are always implemented with flash memory rather than ROM.

And yes - I'm proud to acknowledge - I do go back to an era where computers were repaired with an oscilloscope and a soldering iron.
What's important is to stay abreast of development - especially in a fast moving world such as the one we live in.
