SCSI emulation. After that, Linux CD (Medical web site) writing tools

SCSI emulation. After that, Linux CD writing tools write to it as though it were a SCSI drive. Configuring an IDE CD-ROM for recording If you are using a SCSI drive, you are probably ready to begin recording; CD recording tools in Linux should recognize and be able to use your drive automatically. If you are using an IDE-based drive, however, you may have some work to do. In most cases, your IDE writable CD drive should be recognized and properly configured when you install Red Hat Linux. The following boot option should automatically appear as an option to your bootloader: hdc=ide-scsi This shows that IDE disk device “c”(hdc) is set up to do SCSI emulation. If this is working properly, you should be able to type the following to see if the CD drive appears on the list of accessible SCSI devices. $ cdrecord –scanbus If your IDE writable CD drive is not working, check that the following basic steps are done: 1) have SCSI emulation built into the kernel; 2) remove the IDE-CD module; and 3) add the IDE-SCSI module. By default, SCSI emulation should be built into your kernel, so unless you remove it, there s nothing you have to do there. Here s how you accomplish the other two steps: 1. To remove the ide-cd module, as root user add the following line to the /etc/modules.conf file (using any text editor). options ide-cd ignore=hdc In this example, the writable CD-ROM device is located at /dev/hdc. Replace hdc with the location of your CD device. If you are not sure, type dmesg | grep ^hd to see a list of IDE disks on your computer. 2. Restart your computer. 3. To add the ide-scsi module, type the following command: # modprobe -a ide-scsi 4. To make sure Linux can recognize your CD writer, type the following command: # cdrecord -scanbus Cdrecord 1.10 (i686-pc-linux-gnu) Copyright (C) 1995-2001 J rg Schilling Linux sg driver version: 3.1.19 Using libscg version ’schily-0.5′ scsibus0: 0,0,0 0) ‘IDE-CD’ ‘R/RW 4×4x24 ‘’1.04′ Removable CD-ROM 0,1,0 1) ‘SONY ‘’CD-ROM CDU701 ‘’1.0f’ Removable CD-ROM 0,2,0 2) * 0,3,0 3) * 0,4,0 4) * 0,5,0 5) * 0,6,0 6) *
