> 4GB memory on HP DL380

[Johan Booysen]

hi,

thanks for your reply.

grepping /proc/cpuinfo gives me:

flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat
pse36 clflush dts acpi mmx fxsr ...

so it means the cpu does support pae??

Yes, you need the kernel-pae.

32bit machines support only 4Gb, but if you have a processor with pae
support

# grep pae /proc/cpuinfo

you will be able to run >4Gb with a kernel-pae


#yum install kernel-PAE
