Thanks SWAT very much for your reply.
By the way,I plan to solder at the edge of IDE ribbon cable with the 40 pin IDE device's soldering point, which dreamcast mainboard has,like below «plus.google.com» links
Is there any crucial difference between «just wiring IDE interface» and stick «G1-ATA(IDE) adapter» into slot from GD-ROM?
Does stick G1-ATA(IDE) adapter into GD-ROM's slot" has superior compatibility than «just wiring IDE interface/cable to DC mainboard» for running GDI or ISO image files in Dreamshell ISO?
And Should I try any Bios mod in order to run GDI or ISO image from IDE 40 pin's HDD?
For your information I have a dreamcast which is marked as «IC BD KATANA MAIN V1 Made in Japan» and it has still working GD-rom.
and Can I use any type of diode regardless of specification for this New BIOS MOD?
(for example Can I use Current Regulator Diodes 1N5310 or 1N4148 (100V)or 1N4001,1N4004 for this BIOS MOD?
What is the difference between New BIOS mod and the old BIOS mod?
You said that «you CAN Get Maximum compability » then it means this New BIOS mod would allow to execute more game successfully than old Bios mod in Dreamshell iso?
And what does mean of GPIO 0 5 6 7 on your screenshot?
IS GPIO not the same with pic12f675's pinout like below link and GPIO means specific pinout? pinout-circuits-images.dz863.com/43/PIC12F675.jpg
YOU ARE THE KING in the Dreamcast Hacking Scene!

But There is G1-ATA(IDE) adapter in your site
