+ Goldstar R420 CD-Rom device driver README
+For all kind of other information about the GoldStar R420 CDROM
+and this Linux device driver see the WWW page:
+ http://linux.rz.fh-hannover.de/~raupach
+ If you are the editor of a Linux CD, you should
+ enable gscd.c within your boot floppy kernel. Please,
+ send me one of your CDs for free.
+This current driver version 0.4a only supports reading data from the disk.
+Currently we have no audio and no multisession or XA support.
+The polling interface is used, no DMA.
+Sometimes the GoldStar R420 is sold in a 'Reveal Multimedia Kit'. This kit's
+drive interface is compatible, too.
+Change to '/usr/src/linux/drivers/cdrom' and edit the file 'gscd.h'. Insert
+the i/o address of your interface card.
+The default base address is 0x340. This will work for most applications.
+Address selection is accomplished by jumpers PN801-1 to PN801-4 on the
+GoldStar Interface Card.
+Appropriate settings are: 0x300, 0x310, 0x320, 0x330, 0x340, 0x350, 0x360
+0x370, 0x380, 0x390, 0x3A0, 0x3B0, 0x3C0, 0x3D0, 0x3E0, 0x3F0
+Then go back to '/usr/src/linux/' and 'make config' to build the new
+configuration for your kernel. If you want to use the GoldStar driver
+like a module, don't select 'GoldStar CDROM support'. By the way, you
+have to include the iso9660 filesystem.
+Now start compiling the kernel with 'make zImage'.
+If you want to use the driver as a module, you have to do 'make modules'
+and 'make modules_install', additionally.
+Install your new kernel as usual - maybe you do it with 'make zlilo'.
+Before you can use the driver, you have to
+ mknod /dev/gscd0 b 16 0
+to create the appropriate device file (you only need to do this once).
+If you use modules, you can try to insert the driver.
+Say: 'insmod /usr/src/linux/modules/gscd.o'
+or: 'insmod /usr/src/linux/modules/gscd.o gscd=<address>'
+The driver should report its results.
+That's it! Mount a disk, i.e. 'mount -rt iso9660 /dev/gscd0 /cdrom'
+Feel free to report errors and suggestions to the following address.
+Be sure, I'm very happy to receive your comments!
