1 | Goldstar R420 CD-Rom device driver README |
2 | ||
3 | For all kind of other information about the GoldStar R420 CDROM | |
4 | and this Linux device driver see the WWW page: | |
5 | ||
6 | http://linux.rz.fh-hannover.de/~raupach | |
7 | ||
8 | ||
9 | If you are the editor of a Linux CD, you should | |
10 | enable gscd.c within your boot floppy kernel. Please, | |
11 | send me one of your CDs for free. | |
12 | ||
13 | ||
14 | This current driver version 0.4a only supports reading data from the disk. | |
15 | Currently we have no audio and no multisession or XA support. | |
16 | The polling interface is used, no DMA. | |
17 | ||
18 | ||
19 | Sometimes the GoldStar R420 is sold in a 'Reveal Multimedia Kit'. This kit's | |
20 | drive interface is compatible, too. | |
21 | ||
22 | ||
23 | Installation | |
24 | ------------ | |
25 | ||
26 | Change to '/usr/src/linux/drivers/cdrom' and edit the file 'gscd.h'. Insert | |
27 | the i/o address of your interface card. | |
28 | ||
29 | The default base address is 0x340. This will work for most applications. | |
30 | Address selection is accomplished by jumpers PN801-1 to PN801-4 on the | |
31 | GoldStar Interface Card. | |
32 | Appropriate settings are: 0x300, 0x310, 0x320, 0x330, 0x340, 0x350, 0x360 | |
33 | 0x370, 0x380, 0x390, 0x3A0, 0x3B0, 0x3C0, 0x3D0, 0x3E0, 0x3F0 | |
34 | ||
35 | Then go back to '/usr/src/linux/' and 'make config' to build the new | |
36 | configuration for your kernel. If you want to use the GoldStar driver | |
37 | like a module, don't select 'GoldStar CDROM support'. By the way, you | |
38 | have to include the iso9660 filesystem. | |
39 | ||
40 | Now start compiling the kernel with 'make zImage'. | |
41 | If you want to use the driver as a module, you have to do 'make modules' | |
42 | and 'make modules_install', additionally. | |
43 | Install your new kernel as usual - maybe you do it with 'make zlilo'. | |
44 | ||
45 | Before you can use the driver, you have to | |
46 | mknod /dev/gscd0 b 16 0 | |
47 | to create the appropriate device file (you only need to do this once). | |
48 | ||
49 | If you use modules, you can try to insert the driver. | |
50 | Say: 'insmod /usr/src/linux/modules/gscd.o' | |
51 | or: 'insmod /usr/src/linux/modules/gscd.o gscd=<address>' | |
52 | The driver should report its results. | |
53 | ||
54 | That's it! Mount a disk, i.e. 'mount -rt iso9660 /dev/gscd0 /cdrom' | |
55 | ||
56 | Feel free to report errors and suggestions to the following address. | |
57 | Be sure, I'm very happy to receive your comments! | |
