Thanks for your quick response, Julian. Dear Netters, please pardon me
following this article instead of replying by mail.

Yes, I can agree it 100%. I just put my banner follows. As you can see,
I did set the board DMA emuration of ISA as drq 5 but if it off just
disappear from banner but sympton is same.

: 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 )

: that is what the line "bt0:0 not taking commands" is saying.
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.
