Hi,
Thanks for your Reply.I am using Firewire Card from UniBrain (400 OHCI).
The AsyncRead work only if I read a quadlet.
The Setting for Allocate AddressRange:
Buffer Flags: Use Mdl
Access Type: Read Write Lock.
Notification Options: After Write
Address Range : offset High:0 offset low:0
Address Size :Length:200 Max Segment Size :0
The response that I got: Required1394Offset.Off_high= 1,
Required1394Offset.Off_low = 0.
Then I used the other computer to write to this address. And I got the
famous
blue screen with error number.

What settings have you used for AllocateAddressRange?
Is the AsynRead to the config Rom area working.
What card are you using?
