- Philip's note: I have never done either of the following, and I am not
sure which is the best method. The second method is certainly more
intensive. The first method may only work on an Aero that boots to MS-DOS.

Use some other machine, let's say a desktop, that does have a floppy drive.
Copy or download file SP????.exe to the desktop machine and run it there,
  using its floppy drive as directed.
Copy the files created on the floppy disk to a new directory on the Aero.
Cold-boot the Aero, holding the F5 key to prevent config.sys and 
  autoexec.bat from being loaded and run.
Change to the new directory on the Aero and run the program rompaq.exe.

1. rename your autoexec.bat to autoexec.old
2. rename your config.sys to config.old
3. copy the softpack files into root c:
with the sp files comes another config.sys:
buffers = 20
files   = 15
shell   = a:\rompaq.exe /l:us /!
dos=high
device=\himem.exe
(the shell command is very important)

4. shut down the aero and restart it
5. Follow the instructions

Afterwards:
- Start the aero and hit f8 when you see the message "windows95 is
started".
- Choose Option No. 5. (Confirm Startcommands) Choose 'no' for every
command
except the doublespace driver if you use a doublespace/drivespace drive).
You now start with a clean msdos-screen
- Delete the config.sys
del config.sys
- Rename the autoexec/config.old to bat/sys.
ren autoexec.old autoexec.bat
ren config.old config.sys
- Delete the softpack files in the root directory
