HOW TO?: updage 10.4.9 from JaS 10.4.7

[Spiritzh]

Hi, everyone. Because the driver for my onboard sound card (ALC888) only works on kernel 8.8.1 I need to update my system from 10.4.7 to 10.4.9. I have several question:

 

Can I update from 10.4.7 directly? or I have to go to 10.4.8 first? Where can I get the update package? It seems there're too many options, I am confused.

 

Could someone provide a guide please?

 

My machine:

Celeron D 3.06G

3G DDR2 667 (Dual Channel)

Asrock 945G-DVI

160G SATA HD

 

Thanks.
