Here is what I did to get a Sony Vaio PCGA-CD51 external 16x PCMCIA CD-Drive to work under DOS (on a Toshiba Satellite 1640CDT). ****THIS WILL NOT WORK UNLESS THE MODIFIED CONFIG.SYS FILE HAS BEEN PUT ONTO THE FLOPPY!**** You may need to go into Explorer>>tools>>folder options and enable viewing of 'hidden files' and 'system files' to see CONFIG.SYS. If you are having problems rename CONFIG.SY_ so it overwrites the non-modified file. -------------------------------- 1. Take a blank/error-free 1.44MB floppy disc and make it bootable. To do this--In Windows 9x format a floppy using the 'format a: /s' command in start>>run, or in XP in 'my computer' right click on 'A:' and go to 'format' then 'create MS-DOS boot disk'. Then extract the 'pcgacd51_dos_working' folder to the floppy. (remember to extract the files and not the folder to A:\ for example, so it's A:\FDISK and not A:\pcga-cd51boot\FDISK etc). PLEASE NOTE: ENSURE CONFIG.SYS HAS BEEN COPIED TO THE FLOPPY DISK AFTER MAKING IT BOOTABLE - CLICK 'YES TO ALL' TO OVERWRITE ALL FILES ON THE FLOPPY. -------------------------------- 2. Make your notebook boot from FLOPPY (you may need to go into your BIOS/setup and in the 'boot chain' set FLOPPY to 1st boot device). -------------------------------- 3. The floppy disc should now be bootable. Restart your system with the floppy in the drive. -------------------------------- 4. When asked, hit option '1' to 'start computer with CD-ROM support'. A couple of warnings may appear but ignore them. CONFIG.sys then routes DOS a path to the PCGA-CD51 drivers [va16cd.sys, va16365.sys and va16cli.sys] - DOS should then look for the drive and hopefully it will show some sign of life. -------------------------------- 5. IF the drive is recognised it will be assigned path D: or E: (so if you want to run Windows 98 setup type D:\setup with the CD in the drive). Type D:\DIR to see a list of the files in the CD. -------------------------------- 6. Good luck! PS. This worked for me, as I am no expert in DOS please bear this in mind! Please leave feedback for this file to help others.Download Driver Pack
