It's not a forum for discussing "my issues." If you want to continue
discussion, counterargument following:

1. According to 'man ata' DMA is enabled by default on Solaris 10. To my
experience with Sun W1100z it holds true.

2. 'man eeprom' does not provide any information about DMA settings.

3. SPARC Solaris *is* capable of DMA on ATA. To my experience it holds
true on Solaris 8 with Pioneer DVR-106: CPU load and performance was
adequate in my DVD recording tests and I never had any problems engaging
buffer underrun protection. Negotiated settings for every device can be
verified with 'prtconf -v'. A.
