Hi,
unfortunately I'm using an old SCSI-adapter (Tekram 390UF). The necessary module -ncr53c8xx.ko or sym53c8xx.ko - isn't included in the kernel modules. Is there a workaround to load the module ncr53c8xx or the sym53c8xx on boot?
Can I use any precompiled module for a 2.6-kernel?

Hi, I am making a LiveCD (of my work on localization) based on knoppix. The problem i have with Knoppix-installer is as follows. When i INSTALL knoppix, the installer just ignores all the other OS installations on the hard disk and creates a Grub menu that contains just the new installation.
I have made some changes to the install script boot-tools.bm so that it scans hard disk partitions for other installations and make entries for them in the new Grum menu. Its not tested.
'''I would like to know if there would be any improvements to knoppix-installer in the near future related to this.'''
