Sorry no. I stay away from those SFF of that era from certain companies as they were designed for commercial office use and are "throw away" when they die, the only thing standard is the HDD and RAM..
If you still have the original CD/DVD drive I suggest you try to track down the actual manufacture as there may be a similar model that will work...with the proprietary BIOS....

I do. I'm not sure if the BIOS ever stores the model of the original drive or something so if a new one is installed with a different model, it wouldn't work... but also I'm not quite sure either way. I'm honestly confident the BIOS could be modified or the check could be disabled somehow but again I'm not sure how all of that works. :^)

Whitelists are generally based on PCI IDs but of course that's not a thing for disks, if there really is one* it's probably based on the ATA(PI) identity data... that's assuming they didn't go as far as having custom firmware with custom commands on the drive (which frankly is not implausible, the Sandybridge Dell 7010 I'm using right now has a custom version of a Samsung laptop drive, albeit with apparently no functional differences)...

* May it be an equally stupid configuration affair? I have a Teac CD drive with an actual 44-pin IDE connector instead of that weird thing that's standard on IDE laptop drives, on the side you can find the jumper connectors (like on a 44 pin HDD) but they're nonstandard, with no jumper (which should be master) the drive works as slave and that's only if I don't have a master connected...

Phoenix is not the worst bios to modify or even to use (see Insyde) but not as much as AMI/Award, and even then dealing with compression is a pain...

You're right about the "security." That's incredibly stupid and doesn't affect security at all.

I've never heard of this happening outside of game consoles. I'm curious about this since I have an HP laptop that won't detect my known-good slim IDE optical drive. I never would have thought that optical drives would be whitelisted, especially not to make the system "completely secure" with an exclamation mark.

🤣 yeah the missing TPM and cannot change the CD/DVD player is a security feature.... NOT !
"5. Completely Secure! CD-ROM, DVD-ROM, CD-RW or Combo Drive can no be changed." What kind of grammar is that hahaaa

Yeahhh I do not get that AT ALL. I don't see how the optical drive being tied to the machine would make it "secure"... if anything it would make it more of a paperweight than it already was...
I've attached the BIOS file (zipped) in case you all wanna take a peek at it. I believe its AMIBIOS 7??

The thing is a normal D510 SFF will accept any old drive and basically the same size. I guess given the E-PC is a low cost variant they were making sure once warranty was over a sale of a new PC was "secured"

Yeah, it also seems like it was carried over from the Vectra line when HP acquired Compaq... but yes it is weird. If it weren't for the stupid CD-ROM lockout it would make a nice Win98SE machine.

Did you try another Compaq branded drive?
I had the experience with Proliant servers that can only boot off their Smartstart configuration CD from a Compaq branded CD-drive.
They do not use ordinary CD-boot, so it might be a different issue,but might be worth a try.
Usually these office desktops are much more reliable than their home pendants, as they were designed for 24/7 uptime despite temporary use only.

Yes I tried another HP/Compaq branded drive though this machine was from months *before* the merger. The lockout carried over to the D510 e-pc and that's the only mention of the lockout that I could find in HP/Compaq's documentation.

The BIOS looks for the firmware of the CDROM.
You need to repair the CDROM drive not replace it.
I never tried to flash the firmware to another similar model. But after all these years Im not sure if I would bother looking for one then go through all the trouble to flash it just to find there is something else stopping you from getting the BIOS to see it.
