I am using Redhat Linux 8.0 with the kernel version 2.4.18-14 on AMD system. My board is of PCCHIPS M810DLU v7.5c.The processor is AMD DURON 1800+. I have recently installed Linux and got problem with it. The linux doesn't detect my Soundcard which is of C-Media 9738s, it also does not detect my PCI soundcard ESS Maestro-3 (1980s). I have tried many thing but nothing. I have tried many commands like lspci, cat /proc/pci and got error message like no such directory or file, no such command. I have checked that both are compatible with Redhat linux 8.0. Kindly please tell me what should I do? Please help me, please!.....

Try running:
/sbin/lspci
and:
/sbin/lsmod

Post the output of these two commands here, then maybe someone can help you.
