Extended Memory size

[chaand]

how we can read the extended memory size, memory having size above 64MB

[mindvnas]

you could do direct memory probing, it works in 99.99% of all cases. i think this is how linux and windows do it...

Well, you can as well detect the memory chips, and read them, but this is hardware specific stuff: RIMM, DIMM would have to be read differently.

What i need is i need to get the extended memory awailable from dos using program c or asm

[chaand]

I got the answer

i can be possible using the int 15h function ax = e820h
