the 5.25 and 1.44 are your floppy disks, and the 3.5 is your HDD.
ok i didnt realize that your bios wouldnt have that option.
what you're gonna want to do is set that to 1.44, get 2 floppy disks, and goto wherever you downloaded slackware from. if it was via FTP, you should see two folders with the other slackware files called "bootdisk" and "rootdisk". in the bootdisk folder you want to download the file "bare.i", and download the file "color.gz" from the rootdisk folder. also download the .exe file there called "rawrite.exe". from the command line in windows, navigate to wherever you have all 3 files[make sure you have a floppy disk in the drive] and type "rawrite bare.i a:", when its done put another disk in and type "rawrite color.gz a:". label them "bootdisk" and "rootdisk", respectively. pop the bootdisk in the machine you want to install linux on, follow the instructions. it will tell you when to put the rootdisk in, and eventually ask you if you want to install from a slackware cd. that should do it for you.
