Linux-2.2.x-BUG(?) memmory not detected

[Anton Altaparmakov]

Hi,

Just noticed that both 2.2.18pre21 and RedHat-7.0-patched-2.2.16 kernels 
only detect 64Mb out of 192Mb RAM on my Dual Celeron/Intel 440GX chipset 
based workstation. - I haven't tried any other 2.2 kernels on that 
particular PC so maybe this is a general 2.2.x thing.

The setup is one 64Mb SDRAM and one 128Mb SDRAM so it would seem that the 
128Mb one is not detected at all.

All 2.3/2.4 kernels I have tried have always detected the full 192Mb RAM.

Is this a known feature or a bug? - If I can supply any more info to help 
track this down just let me know what you want to know and I will be happy 
to obtain the information from this PC...

Regards,

         Anton

It's a bug, but in the mobo. Some motherboards lie about its installed ram.
2.3+ kernels have a workaround for detection, but in 2.2 you still have
to manually add <append="mem=128M"> in your lilo.conf file.
