Sil3112 v4.2.83 SATA bios for A7N8X-E

== this post is specific for my case[Asus A7N8X-E Deluxe with Seagate SATA2] ==

What's happens before?

After try many options in bios, grub. I found the way to install winxp on SATA2 and A7N8X-E.

To enable booting winxp from bios, I need to flash neoplus mod bios, link below.
Asus A7N8X-E Deluxe 1013 BIOS with added v4.2.83 Sil3112 (SATA) BIOS by NeoPolus (based on Trats BIOS)

This bios come with new SATA bios(v4.2.83) make xp installation go smooth but afterthat I can't restore grub. Very strange, even I try to reinstall ubuntu. Live cd's not recognize prepartition on the drive. Actually I have sda1 is winxp(just install it),sda5 is ext3(/),sda6 is swap and sda7 is data(ntfs).All partition can be seen in winxp but for live cd the drive appear as a 80GB drive no partition on it.

UPDATE[10/05/2007]: Last night I use Computer management in xp to see partition table on SATA drive and found that there is something wrong i.e. look like it has 25GB excess free space go between swap(sda6) and data(sda7). Live cd think SATA is about 100GB (actually it's only 80GB) and go crazy. I delete that partition include / and swap to make free space on drive, restart and boot with Live CD again. This time every everything work fine.

Fixing sendmail take a long time to start

I notice that my database box[FC6+Oracle10.2] take along time to startup. Sendmail and sm-client very very slow to start[ about 5 minutes ]. There's something wrong in /etc/hosts file. 'newalises' command take long time to update and finish with error below. [root@ora10g ~]# newaliases WARNING: local host name (ora10g) is not qualified; see cf/README: WHO AM I? /etc/aliases: 76 aliases, longest 10 bytes, 765 bytes total [root@ora10g ~]# cat /etc/hosts # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost 192.168.1.55 ora10g [root@ora10g ~]# To fix this, custom hostname[ora10g] need to append to localhost line in /etc/hosts.

Too many open files

Last week tomcat log file report many error about "Too many open files" when it has high traffic. Some in catalina_log say 2007-04-07 16:13:40 HttpProcessor[80][272] Starting background thread 2007-04-07 16:13:40 HttpConnector[80] accept: java.net.SocketException: Too many open files and here is from localhost_log 2007-04-07 16:13:40 StandardWrapperValve[myservlet]: Servlet.service() for servlet myservlet threw exception java.io.FileNotFoundException: /home/log/mylog_070407.log (Too many open files) This is because too many file descriptors're opened by tomcat. File descriptor can be limited in both system level and shell level. To check maximum number of fd in system type 'cat /proc/sys/fs/file-max'. In my case it is 65536(someone said it should set to 200000). Tomcat error when try to open socket number 272 so I think 65536 is ok for me for now. Anyway if u want to set it add 'fs.file-max = 200000' to /etc/sysctl.conf pnix@pnix-a7:~$ cat /proc/sys/fs/fil
