My options for a modded PS2 with a HDD

[Cyber Akuma]

I have a V4 PS2, I heard that the best modchip for this PS2 that is actually still being made is the Duochip.

I have three questions

1. Can this chip boot everything with no swap? Thats really what im going for in my choice of modchips.

2. Is this chip reliable for a V4? This chip hasent been known to cause problems or break down often has it?

3. Will I be able to install and use a HDD in my ps2 with this chip in it?

I read the sticky threads but coudlent find any info on the Duo chip or using it with a HDD.
