I have working boot disk but how you can see there are 5 possibilities: menuitem=CD, Start computer with CD-ROM support. menuitem=NET, Start computer with Network support. menuitem=GIGNET, Mode ONLY for Intel Gigabit network support menuitem=NETCD, Start the computer with CD-ROM and Network support. menuitem=NONE, Start the computer with basic system. and i need only 3 my config.sys looks like that: [menu] menuitem=CD, Start computer with CD-ROM support. menuitem=NET, Start computer with Network support. menuitem=GIGNET, Mode ONLY for Intel Gigabit network support menuitem=NETCD, Start the computer with CD-ROM and Network support. menuitem=NONE, Start the computer with basic system. menudefault=NET,30 menucolor=7,0 [CD] device=himem.sys /testmem:off fileshigh=30 buffershigh=15 dos=high,umb stacks=9,256 devicehigh=ramdrive.sys /E 4096 lastdrive=z device=oakcdrom.sys /D:mscd001 [NET] device=himem.sys devicehigh=ramdrive.sys /E 4096 device=emm386.exe DOS=HIGH,UMB,AUTO SHELL=A:\COMMAND.COM /E:1024 /P STACKSHIGH=0,0 FCBSHIGH=1,0 FILESHIGH=60 BUFFERSHIGH=15 lastdrive=Z devicehigh=ifshlp.sys [GIGNET] device=himem.sys devicehigh=ramdrive.sys /E 4096 DOS=HIGH,UMB,AUTO SHELL=A:\COMMAND.COM /E:1024 /P STACKSHIGH=0,0 FCBSHIGH=1,0 FILESHIGH=60 BUFFERSHIGH=15 lastdrive=Z devicehigh=ifshlp.sys [NETCD] device=himem.sys devicehigh=ramdrive.sys /E 4096 device=emm386.exe DOS=HIGH,UMB,AUTO STACKSHIGH=0,0 FCBSHIGH=1,0 FILESHIGH=60 BUFFERSHIGH=15 lastdrive=Z devicehigh=ifshlp.sys devicehigh=oakcdrom.sys /D:mscd001 [NONE] files=60 stacks=0,0 buffers=30 lastdrive=Z
