I have installed solaris9 08/03 in the first parmary partition,there is a strange problem when I boot the system
If I succeed in boot the system succe at the first time,I will be defeated at the second time,but I will succeed at the third time and then defeat at the forth time ,and so on.
Monitor display as follow:
SunOS Release 5.9 Version Generic_112234-07 32-bit
Copyright 1983-2003 Sun Microsystem,Inc..All right reserved.
Use is subject to license terms.
(If I succeed,the information will be cleaned and system will be normal booted. If I defeated,there will be some waring information at the bottom as follow and nothing response)
Waring:/pci@0,0/pci-ide@1f,1/ide@0(ata0);
timeout:abort request,target=0 lun=0
Waring:/pci@0,0/pci-ide@1f,1/ide@0(ata0);
timeout:abort device,target=0 lun=0
Waring:/pci@0,0/pci-ide@1f,1/ide@0(ata0);
timeout:reset target,target=0 lun=0
Waring:/pci@0,0/pci-ide@1f,1/ide@0(ata0);
timeout:reset bus,target=0 lun=0
I have to press reset at the time.The system will be normal booted next time.

Somthing to try
I have noticed that on some mother boards that if I disable PnP then things work a lot better

Thanks!
But my mainboard's CMOS have no option for this.my mainboard is gigabyte 8iexp.

Check the DMA settings in your BIOS.

What DMA do you say,harddisk?I user "auto" to this option.
How to modify the option,and what is the reason maybe?

it actually appears as though solaris is having a hard time accessing and recognizing the hard drive. If you can boot into single user mode, and use the drvconfig and disks command, this may help...
