Hi, Unfortunaly, it needs to try to boot from the USB CD before it ever looks at config.sys Config.sys & autoexec.bat are not looked at until it boots. Is your BIOS set to boot from USB? M2 If at first you don't succeed, you're about average.

Mechanix2Go I have no idea what you talk about. Of course I have set the BIOS to boot from USB.

Could some please help with this. I am trying to boot a toshiba notebook with external cd rom and floppy drive. I have created my config.sys [CD] device=usbaspi.sys /v /w device=usbcd.sys /d:usbcd001 device=himem.sys /testmem:off autoexec.bat @ECHO OFF set EXPAND=YES SET DIRCMD=/O:N set LglDrv=27 * 26 Z 25 Y 24 X 23 W 22 V 21 U 20 T 19 S 18 R 17 Q 16 P 15 set LglDrv=%LglDrv% O 14 N 13 M 12 L 11 K 10 J 9 I 8 H 7 G 6 F 5 E 4 D 3 C cls call setramd.bat %LglDrv% set temp=c:\ set tmp=c:\ path=%RAMD%:\;a:\;%CDROM%:\ copy command.com %RAMD%:\ > NUL set comspec=%RAMD%:\command.com copy extract.exe %RAMD%:\ > NUL copy readme.txt %RAMD%:\ > NUL mscdexe.exe /d:usbcd001 with the rest as per 98 boot disk. My machine boots and loads the controllers, finds 2 usb devices but seems to hang on the 3rd device. If I unplug my floppy drive the following is then displayed ASPI Device : ID:0 LUN:0 = NU CDRW/DVD SBW242U U301 (NU is the cd rom make so I assume it is seeing the device) Corrupt or missing: usbcd.sys, ramdrive.sys..... error config.sys line 10, line 20.... The above I understand is due to me unplugging the drive and the files not been able to load but this is the only way to get past the the hang stage. Please help !!!!
