How To Create USB Dos Boot Disk

  As we know, if an USB can be boot, the boot file must locate at diskface 0 trace 0. So we cannot create a USB boot disk though simple copy. This article will use HPUSBFW to format USB.
 
1, You can find HPUSBFW in HP driver download website. it is contained in all HP's desktop or laptop "BIOS Update" installer , for example: http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=us&prodTypeId=321957&prodSeriesId=4138087&prodNameId=4137878&swEnvOID=1093&swLang=13&mode=2&taskId=135&swItem=ob-92523-1 .Download the installer "sp***.exe" then extract it though command following:
[code= shell; auto-links: true; collapse: false; first-line: 1; gutter: html-script: light: ruler: smart-tabs: tab-size: 4; toolbar:">C:\Tools\sp52278.exe -e -fc:\tools –s

 

You can see HPUSBFW.exe is under c:\tools folder.

 

2, we need prepare MS-Dos files: MSDOS.sys, IO.sys and COMMAND.com. you can find them in windows 98 system directory (I didn't try it). Or you can download MS-DOS 7.1 (IO.sys version which I use is November 28, 2003).

 

3, Connect your USB with Computer, run HPUSBFW, set like following picture:
