Thanks for the reply. I have already tried two different floppy drives. Both had their original belts completely worn out and I have tried two different new belts in each drive, with no luck. So that's not an option for me otherwise I probably could have sorted this out very easily with the rompaqs …

this is not meant to be critisism in anyway, but more my thinking. Compaq Bios is so terrible, that non system disk or disk error can mean anything. Copy Pasta If you plan to do a fresh installation you must start with a blank hard drive and then install and partition it for the Compaq BIOS via " …

I have been using SD to IDE adapters alot. Might be worth a try as well (have not tested on this specific machine yet. You should then be able to just write my image to a 1GB sd card in theory 🤔 Something like this: https://www.ebay.com/itm/Scheda-SD-Micro-SD-a-2-5-pollici-a-scheda-IDE-a-44-pin-per …

If not then I'll see how much will I have to continue trying to revive the laptop else I might just get rid of it. I have been using SD to IDE adapters alot. Might be …

You'd order boards from a PCB manufacturer like PCBway, JLCPCB or another like that. They're usually not cheap in the UK/US etc, but the Chinese PCB makers are quite cheap. Then you'd need to order the parts in SanguineBrah's post and solder it all together. It might be nice if an adapter like this …

This is a late reply but the Compaq LTE Elite only support 1gb CF cards or smaller. Anything larger than that will give you trouble/not boot. I used anoter laptop to install dos/windows setup files on the CF and then transferred it to run/install on the LTE Elite. It worked. This guy made some …

PATCHMEM + 2GB of RAM = Duke3D works! I have added an update, PATCHMEM now has a config where RAM is limited to 2048 MB of RAM. This allows DOS4GW games like Duke3D to work. The previous limit of 2458MB (or there about) caused errors, while simpler games like Keen 6 worked. So this increases …

On my own system 512MB indeed works for most but not all, 256MB is safer which is why i use 512MB inside 98 and 256MB inside DOS. Might even lower it further in the future on my own config since does really doesn't need that much. I'm tempted to include a set of batch scripts that will update the …

Using patchmem when also limiting RAM to 2458MB allows many DOS games to work and use Sound Blaster sound. Like Keen6 or Stunts. BUT games that rely on dos4gw (or dos32a) do not work regardless of what version I try etc. Like Duke3D or Doom. I get the error "DOS/16M: Error message [6] Not enough …

I also had issues with Rloew's before, but judging the patch set it contains quite a lot of stuff for something that can be done pretty simple (Although a proper pack would be valuable). But of feedback from personal experience, NUSB is not the best USB driver you could use. That credit goes to …

His patch didnt solve my issue getting the Sound Blaster DOS driver to work in Windows when I was testing with 4GB RAM. Also his patch aims to support using more RAM I believe in Windows 98, while my goal was more a compatibility thing. So in my case I limit Windows to only see 512MB. I can do some …
