- Hello
-
- After a little work I have a Bug Fix for CDFSsoftATAPI v.1.23 (31 Mar 1995)
- (RISCOS 3.6 version). I am not sure if the bug is the fault of my six speed
- Aztech CDROM or the module, but one of them is not truely ATAPI!!
-
- This small change fixes two bugs
-
- 1) "Compact disc Faulty " error with any data CDROM on the aztech drive.
-
- 2) " Not an audio track" error. This mainly occurs with sampleCD
-
- The bug is in the CD_SetParameters code. This fix prevent the errors being
- generated. The actual error is generated much lower down in the code &1598.
- This piece of code is used by mamy other CD_ SWI's so it cannot be changed here.
- This fixes is not the best solution to the problem but it seams to work.
-
- Using !ZAP get the module and goto &484 change the BVS &8D0 to MOV R0,R0.
- Save the Module to !boot.choices.boot.PreDesk
- Reboot machine
- All should now be okay.
-
- I still have a problem with large files eg. >490k. When I drag a JPEG to
- !changeFSI the JPEG will be corrupt. When I copy the JPEG to harddisc and
- then to !changeFSI it will be okay. This is not effected by changing the
- buffersize.
-
- When using SampleCD I find I have to use the following sequence :
- Click on Play
- Set Start (0 00:00:00 does not seam to be valid)
- set Length
- Click on stop and then wait
- Drag icon to disc
-
- This fix has only be tested on my machine with my hardware! It might not work
- for you.
-
- There does seam to be a verison 1.30e floating about but it also has the same
- errors for me.
-
- CDspeed thinks it can get 1.367Mbytes/second off my CDROM !!
-
- Hope this will help some people
