This is useful for things such as flashing graphic cards or flashing a BIOS when a floppy drive isn't available to use.
First, you need to download some Windows 98 boot disk files and the HP Disk Storage Format Tool from the attachments below.
Extract both .zip files to a location. Best to create a folder for the Win98 file as there's quite a few files.
Insert a USB pen in to a USB slot - Don't use one that has information on that you need as it's going to get formatted.
Open up the HP USB tool that you downloaded, it should look like this:
Choose the USB drive to use from the drop down menu at the top if you have multiple USB drives connected and the file system needs to be FAT32.
Then in "Format Options" choose "Create DOS startup disk" and browse to the folder where you extracted the Win98 files. Just highlight the folder they're in then click OK.
You should have something like this:
Click "Start" and it will format the drive and once it's finished it will then be bootable.
