Old Dell Latitude LM problems with OS!

Aloha dudes and duddettes,
Okay i posted awhile back that i had a Dell XP. i found out that the m*ther F*cker way too old to do anything. anywayz, i got another old Dell lap top. Its a Dell Latitude LM. its running the old Windows NT OS and i wanna run either EinXP, or Win 98 SE. thing is it is not recognizing the CDROM. in bios it doesn't recognize the CDROM but the floppy. Thats the question. THE LAPTOP HAS NO FLOPPY!! just a hard drive and the CDROM drive! how can i load the Win98 SE CD without the CDROM? is there any way to install a new OS? i need to take out this outdated Windows NT and put a new OS. blank out the harddrive but and start new? but how can i do that? PCMIA cards? but how can i install the drivers? any help is appreciated.

Mahalo,
Scotty

Thanks and mahalo,
