Formatting Compact Flash for DOS

I'm trying to format a 32MB and 256MB Compact Flash card for DOS but have not been successul.  The steps I am taking are:
1. Boot workstation up to DOS 6.22
2. CF Reader connected to workstation with CF inserted
3. Workstation boots to A Drive
4.  CF is C: drive
5. Issue the command format c: /S
6.  format is reported as being successful
7.  When I try to boot off the Compact Flash the message "missing operating system" is displayed.
Any ideas as to why this is happening or any ideas on how to format Compact Flash for DOS?
Thanks,
Adrienne

Did you use FDisk to create a bootable partition on the card first?

Hi,  ok that worked for the 256MB CF but I'm still having problems with the 32MB CF. I first fdisk and then recreate the primary partition and follow the steps above.  When I try to boot, I get "Disk Boot Failure".  Any ideas, this is just for th 32MB CF?

Thanks,
Adrienne

The smaller cards seem unpredictable for formatting to boot.  Try either fdisk/MBR or using fdisk to format as FAT-16 rather than DOS6.22's FAT-12 (try a Win98 Bootdisk to do this and choose the FAT-16 <32MB version))

Great, thanks for the information I'll give the Win98Bootdisk a try over the next couple of days..
