Re: Tuning kernel paramters
First, your conversion to decimal is wrong:
0x90000000 => 2415919104
0x40000000 => 1073741824
Why not specify what you want in hexadecimal, anyway?
Regards!

Re: Tuning kernel paramters
You can use ksh to do that: (sh only handles 32 bit ints)
typeset -i10 x=16#90000000; echo $x
I'm still not sure why you got a syntax error.
