we have a usb pendrive 512 MB and want to use it as bootdevice. we've prepared it with sys under W98, plug in, booting, setting the usb device in the bios at first place (under Hardrive it is recognized as USB stick). always getting errors like " operating system not found" or anything else. At the same PC we can boot from a USB external CD ROM with bootable CD (same W98)
what is the difference between USB Flash and USB CDR. We have tested it with 3 USB Memory Sticks on 5 differnt PC's and laptops. Message differs but result is the same > no possiblity to boot
Searching the internet I only found terms that BIOS has to support USB Boot. I can boot from USB but not from USB Flash Disk.
Any really good ideas. I've spended 8 hours in testing and searching
If possible send answers also to guenter.matthaeus@hdi.de because my normal account I can only read once a week

Did you format it as a system disk? Just doing SYS driveletter:\ isn't good enough.

we've tried this also didn't work but.....
we have found one drive that is doing what we want.
plug it - format it with system parameter - change the boot priority in BIOS - rebooting - works
The stick is a 256 or 512 from http://www.pendrive.com
why others don't work ??????

The difference here is that the cd is a bootable drive,whereas the USB falsh,you will need the necessary space to partition and format the drive with the operating system startup files,you could try loading the startup files on the usb falsh to see if this would create a boot disk.
