I have a 486 SX 25 running Windows 3.11. The Reveal CD Rom 4X drive works ok in dos but in windows it returns with a "no disc in drive" message. I have removed all references to the cd rom in the Autoexec.bat and Confis.sys files and then reinstalled the software (latest drivers from this site) The mother board has only one ide connector and the Hard drive is set as master with the CD Rom as slave. Any suggestions????
