<bigger> Hi,
In response to your mail I am now able to provide you some help in
debuging
the tmscsim.c driver for the tekram SCSI card DC390
{
Note : I have tried the last DC390 driver ( 2000/01/XX )
and the result is even worse !
Once all the driver information have been displayed, the shell's prompt
doesn't appear any more and all commands to the CD-ROM drive are
ignored.
}
here is the apropiate "dmesg" result :
--------------------------------------

[OK the cd is mounted]
I don't have acces to any other SCSI card so I can't say if the probleme
is
specific to the DC390 series or not...
