leirbag: i use a fmv card yes but i have a switch for the fastmem and as soon as i use the fmv it disconnect the 8mb jumper and swith to 4mb! , very easy..
and how to install os3.9 , well i advice you to check out the other threads here on amiga.org , but i will tell u here the basics , some versions of the CD (3.9) needs you to install the Recovery disk FIRST and then boot with that! , yeah it sounds insane but thats what i had to do, but then again thats what i always do as thats what the docs say
when you do that then the "libs" problems wont appear after install , this is because its locked when in use and the 3.9 installer locks it for some weird reason.
anyway more answers in the os3.9 and exec threads recently discussed here on amiga.org
also, i use SFS and a idefix EIDE99 in my sx-1 ..
cheers
