- Thanks for your quick response, Julian. Dear Netters, please pardon me

- Yes, I can agree it 100%. I just put my banner follows. As you can see,

- : do you have another board on the same interrupt?
-
- I did check it again and change to other interrupt number, but it same.
- Also I attempt to follows.
-
- o Level/Edge Interrupt
- o EISA Bus Burst Cycles
- o Initiate Sync ( Should be not related )
- o Sync Date Rate Allowed( Should be not related )

- I think you are correct but I want to figure out that either BT742A
- firm ware (Vesion 3.30) forget to do interrupt nor driver missing
- interrupt. I am not familia with this board and no technical manual.
- So I want to know this timeouted ccb is either finishd or not yet by
- BT742A. Becacuse in btinter routine, If port status is NOT 0x?1 just
- return with 1. If port status is 0x?1, he try to search a active
- (!=BT_MBI_FREE) mail box and ccb. Case of finding it with ccb, he
- unlink from timout queue and call to bt_done routine. but Case of
- "about 10 times 0x81 port status", he just ignores (Not found active
- mail box with ccb).
-
- 1. BT742A made interrupts but btintr missing
- -> Continue investgation for driver under my machine
-
- 2. BT742A is screwed up under some condition and forget command.
- -> I want to know your version and ask to Buslogic(Busteck)
- about Firm Ware.( Is there any BBS like Adaptec one ? )
-
- : if you can find someone with internet access, you can try the kernel
- : running on ref.tfs.com
- : (there are japanese users, some may be close to you)
-
- Yes, I will. I'm going to ask someone for sending it.
-
- Thank you so much, julian.
