Disabling SCSI during booting

QNX Newsgroups (Archives) qdn.public.qnxrtp.installation

Hello,

I installed QNX on my Laptop, which boots from a internal IDE harddisk.
However, the corresponding docking-station has a SCSI controller embedded in
it for conecting to external devices. In order to speed up booting QNX, I
want to disable the SCSI controller in QNX (scanning for devices on the SCSI
controller takes some time).
Is there a possibility to disable the device in QNX without geting error
messages during bootup(I already removed the driver from the boot-script and
created a new boot-image)?

Thanks a lot

Bernd

Hi Bernd,

Try start the devb-eide driver manually and exclude it from diskboot, i.e. write in build file

devb-eide &
[pri=10o] PATH=/proc/boot diskboot -b1 -D1 -odevc-con,-n4 -xdevb-eide

In my system I don’t see any messages except “Press Space…” for this image. It seems like
detection section is kept, but I’m not sure… I have no any SCSI adaptors…

Or rid diskboot from image at all (of course, you have to start all stuff manually). BTW, there are
2 articles “Making Buildfiles…” at QDN website.

Best regards.
Eduard.
