Question about CD-Rom support in WinUAE
Hi!
I have made a Workbench 3.1 installation and also got the CD-Rom working in the emulated Amiga. Many thanks to Thomas for his great guide I found at this adress: http://thomas-rapp.homepage.t-online.de/uaescsi.html I have a question about this. In the guide at 2.8 it says this: Quote:
Code:
ed devs:dosdrivers/CD0 Code:
MaxTransfer = 0xfc00 My question is, what is this parameter used for? I assume it has something to do with the transfer of data between the CD and the Harddrive. Kind Regards Zed |

MaxTransfer defines how many bytes may be read by one command to the device. If it is too high you'll get read errors or corrupted files.
People who tried to install OS 3.9 know what I mean, because the installer always sets MaxTransfer = 0x1000000 which sooner or later results in "volume AmigaOS3.9 has a read/write error". |

Thank you Thomas for the information.
I have another question about this. What happends if the parameter MaxTransfer is missing in the configuration of CD0. Will it have a default value that is to high? Kind Regards Zed |
