Dear colleagues, I've a the kernel 2.0.36 on a P133, 16 MB RAM, programmed IO SCSI card and a plextor RW4, 2, 20. Try to burn on the fly from an IDE disk to the plextor with piping the result of mkisofs to cdrecord 1.6.1. At 4 speed in dummy mode, I get either underruns or SCSI command failures (cannot fix in dummy mode). Without dummy mode, coasters of course. Anyone an idea ? replace the SCSI with bus master with kind regards, Pieter
