Hi, I've managed to make a bootable CD (Using Adaptec CD Creator version 3.5) but it can only boot with no CD support options. The boot image was created using a MS-DOS 6.0 with a little menu with separate options for ASPICD and OAKCDROM (ie. [menu] menuitem=OEMCD, Start computer with OEM CD-ROM support. menuitem=MSCD, Start computer with MSCD CD-ROM support (OAKCDROM.SYS). menuitem=NOCD, Start computer WIHTHOUT CD-ROM support. menucolor=7,0 [OEMCD] device=a:\himem.sys device=a:\sys\aspi2dos.sys device=a:\sys\aspi4dos.sys device=a:\sys\aspi8dos.sys device=a:\sys\aspi8u2.sys device=a:\sys\aspicd.sys /D:oemcd001 [MSCD] device=a:\himem.sys device=a:\sys\aspi2dos.sys device=a:\sys\aspi4dos.sys device=a:\sys\aspi8dos.sys device=a:\sys\aspi8u2.sys device=a:\sys\oakcdrom.sys /D:mscd001 [NOCD] device=a:\himem.sys [COMMON] files=10 buffers=10 dos=high,umb stacks=9,256 lastdrive=z device=display.sys con=(ega,,1) country=044,,country.sys install=mode.com con cp prepare=((437) ega.cpi) install=mode.com con cp select=437 install=keyb.com uk,,keyboard.sys for all CD options, after the first line device=a:\sys\aspi2dos.sys the loading stop, and I have to reboot. These drivers were taken from the win98 startup disk. The only different from the win98 disk was the himem.sys was not calling with /testmem:off ie. win98 device=himem.sys /testmem:off Anybody know what is wrong? Thanks in advance.

You need to execute the file Microsoft's CD ROM Extension (MSCDEX.EXE) from autoexec.bat file in order to acces your drive. Add the following line to your autoexec.bat file. goto %config% :OEMCD [path]\mscdex /d:oemcd001 {for OEMCD} goto end :MSCD [path]\mscdex /d:mscd001 {for MSCD} goto end

I've got those lines in my autoexec.bat. It works fine on the floppy. All the files on the floppy was marked with READONLY, and had turned the WRITE protection ON to stimulate the condition of the CD while booting (avoid write back). As I said, the only different is the /testmem:off which is not recognised by the HIMEM.SYS of DOS 6.0. Any ideas?

I am having the same problem, i wanna boot off a cd into dos and have access to files on the cd that are not in the boot image, buut it fails to load the cdrom drivers, my cd is basically setup as above, someone please help, there may be something i can heklp u with as well, just ask!! :-)
