Gosh. There are many many many Linux reports on the 4100. Just none on openSUSE-10.3.

This is an old computer ... can you tell us more about it ? From what I could gather from surfing, the processor can be from 866MHz to 1.2GHz, and memory from 128MB to 1GByte. The graphic card could be an ATI Radeon M6 or an nVidia GeForce2 Go. What configuration do you have? This is important in some cases, especially if one is having problems getting the GUI configured properly.

Its not clear to me how far you got in the install. Is this after the first boot (before root and users established) or after the second boot (after everything is configured).

If immediately after the1st boot (and before the second boot, ie before root and user accounts setup) I recommend you try a re-install with each of the alternative installation methods, until you find one that works ... ie "Installation-ACPI Disabled" or "Installation - APIC disabled" or "Installation - Safe Setting" ... failing that, at the installation menu, you could try pressing F3 and go for a VESA or Tex mode install.

If the 1st boot was successful, and this problem is immediately after the 2nd boot, did you try the "fail safe" boot option?

When it appeared to "freeze" did you try <CTRL><ALT><F1>, <CTRL><ALT><F2>, <CTRL><ALT><F3>. to get more error information, or <CTRL><ALT><Back Space> to try and exit the failed X server?
