well, got it installed, booted and flashed on a 1.6 and a 1.0. i did exactally what it says on www.spidergx.com and everything worked fine.
What I did find out however, is that about 50%of the gx's have the same problem as the reg spider,s.. the damn screw hole for the chip is not centerd right. I though I had to hol it down to get it to work... nOOOOO, i had to actually move oit a liitlbe back to where i shaved out a little of the IDE connector so it would fit. this is actually a good chit. it works better then my xeniums and my x-3, its just the problem of getting it to work. I have udgraded 2 harddrives for a buddy, and flashed it and it works fine.
Just read the website, and look at the chip. make sure it is touching thouse lpc holes right. on mine, one of the pogo pins was slightlly off also so I had to force it down and to the side.
thanks spider for not knowing how to cut the damn chips correctly.
Also, there will be a OS update on the site in about 2 days they say.
