I've been using HDAdvance - which, according to Wikipedia, is a pre-pressed (and therefore more limited) clone of HDLoader - for years now in my FAT PS2 with an IDE HDD. It was done for me when I was a kid, but as someone with a love for modding, tweaking and customisability, I've been looking around at the other options, and they seem a lot better; they allow the execution of files other than PS2 ISOs, and the use of themes, as well as out-of-the-box UIs that aren't butt-ugly. I'm thinking...
PS2 softmod - what are my options?
