device driver call during bootup

["anurekh saxena" <anurekh@calsoftinc.com>]

hi,
i was going through the PCI interface in the Linux 2.4 kernel and got very
confused about how the drivers fit into the whole scene.
I understand that the kernel maintains a table starting with the bus and all
the devices and bridges connected to it ,but during boot time when are the
drivers(example IDE,SCSI etc)  loaded . I mean does the kernel call each
drivers startup routine to see if its the correct driver, or is this
information stored somewhere .
regards
anurekh

root file system but when the free RAM approaches around 500 K (which I see
from /proc/meminfo) the ld.so gives a strange problem when I sometimes load
binary by saying

is if I try starting it again after a second or 2, it works fine. I am
unable to deduce if it is linker or VM problem. Can any VM gurus out there
help me? Can linux misbehave when it is low on physical memory?
