Bug#282979: Sun Sparcstation 20, Installation of Sarge netinst failed. Don't detect CDROM

[Yuri Pimenov <up@ftpsearch.lv>]

Package: Sarge
Version: current

I've taken Sarge netinst iso from here:
http://cdimage.debian.org/pub/cdimage-testing/sarge_d-i/sparc/current/sarge-sparc-netinst.iso

It boots normaly, but after "language/region" dialog the installation
stops with message that "CDRom can't be mounted". If I press "Yes",
the dialog appears again and so on. My hardware is ok, I can provide
the full information about the drive (serial number and so on if
needed). Also can run some tests or what you'll say to me to do to
find the right description of the error.

Hardware: Sparc Station 20, 2 x SuperSparc II 75Mhz, 384 Mb memory.

Thanks.
