Does Windows XP 32 bit support more than 2TB partition?

A

No. Windows XP X86 is using MBR which cannot recognizes any partition larger than 2TB. However, Windows XP X64 and Windows 2003 server support GPT, which can support up to 256TB. But, since Windows XP 32 bit cannot recognizes GPT partition, so any GPT volume is "protected" and cannot be read / write in Windows 32 bit.

Follow these steps: parted /dev/sdb mklabel gpt p (Press p and it shows the range of the volume, ex: from 0 to 4198881) mkpart primary ext3 0 4198881 q (Press q to quit, parted automatically saves it to you) mkfs.ext3 /dev/sdb1 mount /dev/sdb1 /mnt

Incorrect CPU Speed. My system is dual AMD 2.2 Ghz, but after install FC4 or CentOS x86_64, it shows my cpu speed is 1000 Mhz.?

A

Once AMD PowerNow is enabled, the driver for powernow-k8 is loaded, and then you can set the cpu frequency. Type "cpufreq-info", it tells you that the cpu range is from 1000MHZ to 2.2 GHZ (min to max), and the cpufreq governor is userspace, which use the minimum cpu speed. You need to change the governor to performance in order to get the maximum cpu speed. Type "cpufreq-set -c 0 -g performance" to set it for cpu 0, and type "cpufreq-set -c 1 -g performance" to set it for the second cpu. But next time you reboot the system, this setting will gone, so you need to add these two commands to /etc/rc.local. You can enter CMOS, Advanced, AMD PowerNow configuration, and disable the PowerNow feature. but these messages will appear in dmesg: powernow-k8: MP systems not supported by PSB BIOS structure.

I try to install FC4 (Fedora Core 4), but it just causes kernel panics or reports some Ram Image Crash. This error happens to all Intel 9xx and Supermicro MBs, any workaround?

A

This is a very weird Linux problem, bugzilla number is: 159026. There is a garbage workaround, simply follow these steps: 1. Type some garbage, or mediacheck in the installation screen. 2. Ignore the error message. 3. Type linux mediacheck or other linux text to continue the installation. If the above garbage workaround doesn't solve the problem you have, try the other suggestions from: http://forums.fedoraforum.org/showthread.php?t=62400

I install Debian, and I configure my second network port, how can I test the network ports?

A

First, bring all the ports down. ?ifconfig eth0 down?, ?ifconfig eth1 down?. Second, bring up the second port, ?ifconfig eth1 up?. Third, add the gateway to the port, ?route add default gw 192.168.0.1? (change the 192.168.0.1 to your network?s gateway). Fourth, check it, ?netstat ?nr?, if it shows the1 and the default router to use eth1, then the final step is to test it, ?ping yahoo.com?.
