Thanks for the tips on creating a compatible HDD. By following your instructions, I've created an empty chd file with 20mb of total storage capacity. I've used the AT486 driver to do a fdisk and format it, and I booted with a dos 3.3 floppy to transfer the system to it. Everything worked fine!
After that, I've converted the .chd into .img in order to open it with PowerISO, to insert the complete DOS 3.3 files and the remaining boot files to the root folder. Saved the .img and converted it back to an uncompressed .chd file to boot my ibm5160 with it. But it prints the same message on screen saying "missing operating system". Do I need to boot ibm5160 from floppy first every time and then go to the hard disk?
Also, I need to know which program may I have to use to maniputale floppy disks. I have ms-dos 3.3 booter disks (dos33.ima and msdos33bootdisk.img) to use with this driver but they are all in 1.44mb 3.5" disk format, and I need to transfer its contents to a single sided 360k floppy disk in order to make it to work with IBM5160 floppy slots. How can I do that?
