Hello again
I had bad luck with the adaptec 2920, it had PCI bus and my computer
use old isa 16 bit bus. The guy at the computer shop offer me an Advansys
ABP510/5150 - Bus-Master ISA (240 CDB). I'm thinking about buying it.
But I found an old ISA controller with the chip NCR 53c80-40,(also got
a Z80 CPU ;-) This controller seems to be bootable with FDC, as I see the
manufacturer of this board was Longshine and the model is LCS-6631 rev:a1.
I am afraid because I don't know the difference between ISA and EISA
bus , one fit on the other slot or not ? Or may be this contrller is for
an old non-compatible computer like Apollo or NCR. The bus is exactly the
same than an ISA.
I don't need that the controller to boot, for that I will use an IDE
cotroller.
I did a netsearch with result just one comment that say:
---adding an large comment found on the net-----
We got stuck with a minor problem in the SCSI driver using the
NCR53C80-40.
In our first version of the driver,NCR5380 chip was used and
the "NCR controlller" is set to DMA mode operation,phase mismatch
interrupt is generated for each "phase" transition.This strategy
has been found to work well with NCR5380.
However with NCR53C80-40 the same driver has been giving some
problems.Phase mismatch interrupts do not get generated for some
phase transition although manual claims that NCR53C80-40 is fully
compatible with NCR5380.
I would like to know if there is any kind of this problem and
if there is any "programming" to be done to get away.
Thanks,
Rajan.

It seems to appear in some mailing list, but not related
to linux SCSI drivers, may be other OS.
Any one could point me how to use this old scsi controller for my
linux box ?
thanks in advance
