Command/Script to find out what hardware is on machine

[Kim Lanners]

Hello,

Is there a command / program similar to Windows 'Device System' which will
report all peripherals? I am interested in having Linux report what it sees
for total RAM installed.

Also, what file do I modify so as to let Linux 7.1 know that there is 128MB
RAM on the system? Would this be the lilo.conf file? I am very much a newbie
and if you could be very specific in your instructions, I would really
appreciate it. ;)

Any help would be greatly appreciated.

Best Regards,

Kim
