Duh, sounds good to me. I'd like to change some BIOS settings without 
having to reboot the whole computer. It seems that syscfg is what I'm 
looking for, right?

I tried to use it, but got nasty segfaults: I basically loop-mounted 
DTK-2.1-LINUX-1109-A01.iso, extracted tools/dell.tar.gz contents, and 
setup appropriated LD_LIBRARY_PATH to add a path to the needed toolkit 
libs (libdchbas32 and libdchipm32). Then I got a segfault trying to run 
syscfg:

# ./syscfg
Segmentation fault (core dumped)

Stracing it gives the following:
-------------------------------------------------------------------------------
open("/dev/mem", O_RDONLY)              = 3
lseek(3, 0, SEEK_CUR)                   = 0
lseek(3, 0, SEEK_CUR)                   = 0
mmap2(NULL, 65536, PROT_READ, MAP_PRIVATE, 3, 0) = 0xb7dc3000
close(3)                                = 0
open("/dev/mem", O_RDONLY)              = 3
brk(0x80e3000)                          = 0x80e3000
lseek(3, -1208236364, SEEK_CUR)         = 3086730932
lseek(3, -1208233984, SEEK_CUR)         = -1 EOVERFLOW (Value too large for 
defined data type)
mmap2(NULL, 65536, PROT_READ, MAP_PRIVATE, 3, 0xb7fbd) = 0xb7db3000
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV (core dumped) +++
-------------------------------------------------------------------------------

I tried on a 6GB and 1GB memory computer (PE and Precision), kernel 
2.6.17.5, 32bits, with dcdbas and dell_rbu modules loaded, same result. Is 
there a limitation about memory?
