Please help me.

Let's take a look at the Linux general technology-Linux technology and application information. For more information, see the following. Ladies and gentlemen, I am a newbie. I installed red hat linux 9 a few days ago. I have encountered some problems. I am very grateful if you forget to give me some advice!
1. The machine has two startup items. What are their differences,
Red Hat Linux 9 (2.4.20-8smp)
Red Hat Linux 9-up (2.4.20-8)
2. encountered this problem when installing the NIC:

Can you tell me the detailed steps for installing the NIC? For more details, I 'd better not post it online.
3. Sometimes my mouse won't move. Just pull it out and plug it in again, which makes me very depressed ..
4. After the installation fails, are the files still left in the machine? Do you want to manually delete the files or uninstall the files?
5. When I select Red Hat Linux 9 (2.4.20-8smp) as the startup item, a series of characters are occasionally played by pressing the keyboard. What is the problem?
Ps: My machine is Asus dual-core, Nic Realtek RTL8168/8111 PCI-E Gigabit Ethernet Adapter (PHY: Realtek RTL8211/8212) PCI, mouse usb
