Need Help about Dreamshell without GD ROM

[pstationBG]

Ok , so finally I had some time to install 2.5" IDE hdd .
So far so good , but I have a few issues .
MX - flashed with " boot_loader_unlock_G1_IGR_dbs.bios " . On SD card > DS_CORE.BIN
on HDD folder DS with all DreamShell files .
After dev box animation I can see the black screen with initialize devices, then black screen and nothing happened .
Need to press "start" cpl times to load "bootloader" , but at the initialize devices screen .
From there loading Dreamshell from SD card , sometimes just stays at black screen but mostly it is loading ok .
Tryed to load Dreamshell from HDD , just added DS_CORE.BIN to it , but can't load it .
