[ltp] problems with memory upgrade

[Stefan Blum]

Hi Tino,
lspci shows
0000:00:00.0 Host bridge: Intel Corp. 440BX/ZX/DX - 82443BX/ZX/DX Host bridge 
(rev 03)
0000:00:01.0 PCI bridge: Intel Corp. 440BX/ZX/DX - 82443BX/ZX/DX AGP bridge 
(rev 03)
so I would think that my X20 uses the BX chipset.
I'll have to wait for the module from ebay to see if it has 2x128MB on it (the 
seller said it would work with an X20...).

Thanks for the detailed answer!

Stefan
