Oh I see. By enabling romvec debugging in OpenBIOS, I can see that it 
looks for a property named "scsi-options" in the ESP node of the device 
tree. Therefore the following patch may persuade Solaris to set this 
option in the ESP kernel module by default:

diff --git a/openbios-devel/drivers/esp.c b/openbios-devel/drivers/esp.c
index 2dfc2bd..d6fa9bc 100644
--- a/openbios-devel/drivers/esp.c
+++ b/openbios-devel/drivers/esp.c
@@ -383,6 +383,12 @@ ob_esp_initialize(__attribute__((unused)) 
esp_private_t **esp)
      push_str("scsi");
      fword("device-type");

+    /* set scsi-options to help Solaris boot */
+    PUSH(0x58);
+    fword("encode-int");
+    push_str("scsi-options");
+    fword("property");
+
      PUSH(0x24);
      fword("encode-int");
      PUSH(0);

Nick - do you think you could do a quick test on this one?


ATB,
