The XCDROM document clearly pointed out, try not to put CDROM drive and hard disk into a single channel, it'll harm the performance. I suggest you move the IDE2 SLAVE hard disk to IDE1 SLAVE and the same for CDROM drive. >Based on my reading of the documents: > >SHSUCDX /D:CDROM,,1,1 /D:CDRW,,2,1 > >or > >DEVICE=C:\DOS\XCDROM.SYS with XDMA under certain conditions. > >in the config.sys file. The latest XCDROM v1.9 have it's own DMA logic, it WILL co-operate with XDMA. But it also work without XDMA (suppose you got a SATA hard disk). >The hardware is a Gigabit PII with an IBM and WD hard disks. >How do I test whether XDMA is needed. Re-arrange the hard disk and CDROM drive, then load: Config.sys: lastdrive=z device=xdma.sys /o (note: "/o" is overlap) deivce=xcdrom.sys /d:shsu-cdn (I use 'shsu-cdn', my habit) Autoexec.bat: shcdx33a /d:shsu-cdn,y (CDROM should be drive Y,Z) Rgds, Johnson. ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
