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.

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.
|

|

|
|
Sometimes the GoldStar R420 is sold in a 'Reveal Multimedia Kit'. This kit's
|
| 20 |
|
|
drive interface is compatible, too.

Installation
|
| 24 |
|
|
------------
|
| 25 |
|
|
|
| 26 |
|
|
Change to '/usr/src/linux/include/linux' 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 dep ; 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 (once for all times).
|
| 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='
|
| 52 |
|
|
The driver should report his results now.
|
| 53 |
|
|
|
| 54 |
|
|
That's it! Mount a disk, i.e. 'mount -rt iso9660 /dev/gscd0 /cdrom'
|
| 55 |
|
|
|
| 56 |
|
|

| 57 |
|
|
Be sure, I'm very happy to receive your comments!
