hi,

after installing rh 9.0, it suddenly recognized my pc as a big mem and an smp... (as it shows in grub menu), but i only have a single axp 2100 and 256 mb ram. take a look at this...

[root@localhost root]$ cat /proc/cpuinfo

and

[root@localhost root]$ cat /proc/meminfo

now i am wondering what kernel update should i download...

To find the version of your kernel, just type uname -r in the console. I don't know if this is what you were looking for. And what was the aim of your question??

linux saw my system as something with 4gb memory, but actually only 256 mb, and it saw my system as a multiproc system, but actually its not... so there must be something wrong, i just can't figure out what it is...

I think your confused:

MemTotal: 254332 kB == 254.332Meg of Memory, not 4G
Mem: 260435968 /1024 = 254332 KB == 254.332 Meg

Swap: 2154979328 /1024 = 2104472 KB == 2,104.472 Meg /2.104472 Gig of Swap space.

if you look at your /proc/meminfo output...
SwapTotal: 2104472 kB
this would be the same as /proc/swaps output... it would also list your partitions it is mounted at:

/dev/sda3 -- on my rh9 install (/dev/hda3 if you have an IDE and not Scsi)

I don't see how you say your system is a multiprocessor...
