OPL can't see the games in HDD?

I've used PS2 SCPH-35006 & MCBoot with OPL v0.8
I've just got the Network Adaptor for HDD
I've installed the PS2 Games with WinHIIP as the guide description
When I open the OPL, There's no game in HDD Games
When I reboot & open the HDloader, the games is there
why & how can i play the games with OPL?

check the setting in OPL if the Internal HDD Feature is enabled .

i think it's enabled

i'm using v0.8 R630 in the setting i used "HDD device start mode" to "Auto" & "Automatic HDD spin down" to 20

is it need another setting?
