That HD2400 PCI is likely too new(2007) to have drivers for Win9X and/or even work correctly in that old most likely 440BX chipset based system. The AGP slot only supports cards capable of 3.3 volt signaling, so if your AGP cards are too new, they won't work. Can you post some pictures or more info about the cards you have to work with?

Well i did find a driver that for the HD2400 pci that said to work on win98,
The pc came with a Matrox MGA-G100A-E, and the ones I tried were all ati and between'97-'03 i think, mostly that have both 3.3 v and 5 v , the only one that i know for sure that i tried was an ati 9600 pro

The HD2400 was an XP/Vista era card, I've never seen any drivers available for Win9X as that was long out of support when the HD2400 came out. A 9600 Pro is AGP 4X/8X only and won't work in your system. I suggest you hit ebay and grab a cheap Nvidia TNT2 or Geforce 2 MX as your very CPU limited and won't benefit from anything faster. You then want to use early Nvidia drivers like 7.76 or so as they have less CPU overhead, and install DirectX 7.

I have like more other other agp cards (untested) that I would prefer to use if possible. One of that links dont ship to me and the other has more shipping cost then the worth of the card. Also id have to save up to buy anything rn

Well then post up pictures or info about all the cards you currently have as that's the only way I (or most likely anyone here) can help you.

Here a list of most of the agp cards i currently have besides the already mentioned Matrox one:
Ati:
- 2x peak 9600 pro
- 9800 pro
Nvidia:
- Point of view MX4000
- 2x point of view fx5200
- Msi fx5200
(List is copy pasted)
As i looked them up i realize they're all 2002-2004, so probably all too new i guess, im gonna look for an older one soon locally hopefully

If they're all untested there's no way of knowing if the problem is with the PC or the cards. Don't you have any other AGP system/motherboard to test? If not, then your best bet would be the Point of view MX4000 since it's pretty much a Geforce 2 and should work fine on Windows 98.

No I don't have another pc or motherboard with agp atm unfortunately, this and an wang 486sx machine (were i cant find any info over on the internet, not the model, not the motherboard, not the chipset, nothing) (i might open another thread about it soon) are the only i have that are old (2007 is the oldest newer pc i have).
The MX4000 gave the same post beebs

That Mx4000 should be a universal 1.5v/3.3v card, so that's odd it doesn't work. The FX5200 is also a universal 1.5V/3.3V card as I recall. Do any of those work? As I recall this particular Compaq doesn't have any onboard video, so a plug in card is necessary to get it going. The problem with the MX4000 or FX5200 is you have to use much newer driver versions that have more CPU overhead that a Celeron 333 doesn't have to spare. Really suggest you try and find a TNT2 or Geforce 2 MX so you can use early drivers. Though if you are just going to play DOS games and not Windows games, then the drivers don't really matter. If you are just going to use DOS even a common S3 or Cirrus PCI card would get you going......
