Hi all,
We are planning to write a QNX device driver
for our PCI Express-to-SCSI/Serial ATA II adapter
device. Our PC platform is Intel Xeon E5620.
We are using QNX 6.5.0.
We have downloaded and checked the Generic x86 BIOS/APIC BSP.
But it doesn’t contain any source code for devb-* components.
From QNX help, we found that devb-mvsata for
Marvell 88SX50XX SATA interfaces support
a device named 88SX6041 which is a
4-port SATA II PCI-X Controller. If we get the source code
for this driver as a reference, it will be helpful for us.
Could anyone tell me where can I get the source code of this
driver or could you please give any reference to existing driver
source codes which would be most similar to this device?
I couldn’t find any documents regarding writing a block device
driver too anywhere. 
Thanks in advance,
Warm Regards,
Lullaby
