So your DHCP option 175 could look like:<BR><BR>0xB2 0x01 0x01<BR><BR>where,<BR><BR>0xB2 : DHCP gPXE encapsulated option 178.<BR>0x01 : The encapsulated option's value occupies 1 byte.<BR>0x01 : The encapsulated option's value is 1 (true).<BR><BR>I do not know which DHCP service you use, so I do not know how you can reconfigure your service to give PXE clients this 'use-cached' option via DHCP.</TT></BLOCKQUOTE></BLOCKQUOTE>
