I could not find neither the floppy drive nor the Cd rom (both proprietary; the floppy is a weird cable and the CD rom use the PCMCIA port); so I am stuck basically.
The computer just boot and expect either a "legacy floppy" (the original IBM external floppy), or the main disk; the bios has nothing else. How do I solve the boot issue? I would like to make it a dual boot (dos and W98) machine; so I can use both environments, but as is now I can't even install one OS. Is there any updated bios that would let me use the CD rom or floppy as boot via USB? Or is there something else I can use to fool the bios to believe that it is using the official IBM floppy or CD rom? I was looking at this to simulate the CD rom; not sure if that would work: it seems that it can use ISO of CD roms as if it was a real drive, and can mount also IMA files from floppy and virtual drives
I haven't tried this though! So no guarantees.
The problem here will be finding another PC that will play nicely with 240's BIOS. ThinkPads of this era are not keen on booting from the OS on a disk installed in a different system.
Getting the proprietary IBM CD drive is about the only way out in my recollection, which may be faulty since I haven't toyed with 240s in about 15 years.

I think the underlying issue is the Thinkpad 240's BIOS and CHS parameters.
Newer computers (and USB->IDE adapters) will just use LBA addressing, but the 240 might still be using some sort of LBA -> CHS translation.
