Description of problem:
I have a sony vaio picturebook with RH 8.0 installed. The Sony doesn't have an
ide floppy. Rather a USB port which a usb floppy can be attached. The bios is
written to boot a floppy via the usb port. 
When the usb floppy is attached, it is recognized. However, make a boot disk
with mkbootdisk results in a floppy that will not boot. If a floppy is formatted
as DOS, written with data and then read on a DOS machine, DOS reports that the
floppy diskette is not formatted properly. It appears that the geometry of the
USB floppy is not being properly calcualted on Linux.

Version-Release number of selected component (if applicable):2.4.18-14

How reproducible:

Steps to Reproduce:
1.On DOS format and write data to a floppy.
2.Inset this floppy in USB floppy connected to Linux.
3.Attempt to mount the floppy.
4.Mount reports numerous partition errors.
1. On Linux perform a mkbootdisk. All appears to be OK.
2. Attempt to boot diskette on VAIO. Bios fails reporting a "Boot Error".
1. mkfs a DOS filesystem on diskette inserted in USB floppy drive.
2. All appears OK.
3. mount the diskette and write data to it whilst still on the Linux system. All
appears OK.
4. Insert fiskette in a DOS system (dos, nt, windows, etc.). The diskette will
not mount. Diskette is reported as not properly formatted or defective.

Additional info:

Since unable to create and use diskette, unable to perform other tasks like
install vmware and create quest operating systems. For me this is a signficant
high priority problem that really needs to be fixed.

A possible workaround might be is I could created bootable cdroms. Where  I
could boot whatever I like.
