Question: Can DOS (IBM PCDOS 2K, specifically) see and access SATA CDROM and DVD drives? My SATA 2.0 HDD is in IDE emulation/interface mode. I have an IDE DVD writer that is assigned a drive letter and is accessible in my DOS (from boot). But at the same time the second DVD writer that I have, a Pioneer 216 SATA drive, doesn't show up, doesn't get a drive letter at boot, and is obviously not accessible. Since my IDE writer is on its last legs, I'm thinking of getting another SATA witer, since IDE will soon go the way of the DODO. But I'll buy another IDE writer if DOS can't access SATA writers. Autoexec.bat: lh c:\dos\mscdex.exe /d:oemcd01 Config.sys: devicehigh=c:\dos\drivers\qcdrom.sys /d:oemcd01 Any ideas? TIA

You need to specify each Optical Drive in the CONFIG / AUTOEXEC **-DOS will only read one drive if you do not inform it otherwise...........

Thanks, Pater. While that didn't solve the whole problem, it did show what I was doing wrong, and aided me in getting to the SATA driver issue. This is now what my config and autoexec files look like to successfully acess both an IDE and a SATA DVD Writer after booting DOS: Config.sys: devicehigh=c:\dos\drivers\qcdrom.sys /d:oemcd01 devicehigh=c:\dos\drivers\gcdrom.sys /d:oemcd02 /c1 Autoexec.bat: lh c:\dos\mscdex.exe /d:oemcd01 /d:oemcd02 The Qcdrom.sys driver didn't work on the SATA drive at all. For that I needed the Gcdrom.sys driver, and now I have both writers/drives showing up as E and F respectively. BTW, the /cx parm tell the driver what SATA channel the drive is on ... c0 for 1, c1 for 2, etc. If anyone else needs the Gcdrom.sys driver, I found the link to it at: http://dougstips.com/PAGES/drivers_...
