Qnx4 Memory limit

Is there anyway of getting Qnx4 to recognise more than 64MB?



It usually just works - ie. I have never had a system which it didn’t figure it out correctly itself. On the other hand, some systems do have problems. You can create a boot image which you manually add the memory if your bios doesn’t report it properly. Take a look at the options you can give the boot program in your build file:

It turns out to be a hardware limitation of the IBM machine I am running QNX4 on. Newer IBMs report a maximum of 128 and the latest ones show the full amount. I just hope the data acquisition machines don’t have this problem!
