N36L dsm 4.2 下U盘不再识别为esata硬盘的修改方法，参考了多个帖子

参照N36L的实际情况，把 /etc.defaults/synoinfo.conf里的参数改为：


修改后能usb正常识别


esata也能正常识别




光驱位sata识别为硬盘6

关于有坛友说dsm无法识别esata，这里贴出一份关于Hacked BIOS的英文原文（http://terabyt.es/2011/07/02/nas ... th-nexenta-napp-it/）
Update BIOS and install hacked Russian BIOS
The HP BIOS for N36L does not support anything but legacy IDE emulation on the internal ODD SATA port and the external eSATA port. This is a problem for Nexenta which can detect false disk errors when using the ODD drive on emulated IDE mode. Luckily an unknown Russian hacker somewhere has modified the BIOS to allow AHCI mode on both the internal and eSATA ports. I have always said, “Give the Russians two weeks and they will crack anything” and usually that has held true. Huge thank you to whomever has modified this BIOS given HPs complete failure to do so.

I have enabled this with good results. The main one being no emails from Nexenta informing you that the syspool has moved to a degraded state when it actually hasn’t

You need a USB stick with at least 512mb free (maybe less) that you don’t mind formatting.

BIOS update 17/01/2011 (A) 27 Feb 2011 from HP – This is used to create the USB stick for the BIOS flash. Don’t download the newer version – it’s unknown if the hacked BIOS is a patch or a complete replacement. Safer to make sure you download SP52016.exe (2.6 MB) which is the BIOS the hack is designed for

Hacked BIOS with AHCI support – This file goes on the USB  stick also.

The summarised instructions below originally come from user GMCinema from the this thread;

1.Execute the HP install file and let it prepare your USB stick – follow the instructions on the web page that pops up after it installs.
2.Copy the unzipped O41_AHCI.ROM file (after extracting from the zip file) to the same USB stick
3.Copy the “flash.bat” file onto itself in the same directory and rename to “ahci.bat”
4.Open “ahci.bat” in a text editor and replace the ORIGINAL.ROM filename with the O41_AHCI.ROM filename, save (should look like this: kbd /”flash O41_ahci.rom -r 100000,10000 -r 1e0000,10000;q”)
5.Put the USB stick in and boot from it (you’ll need a monitor and keyboard obviously)
6.Restart server – it will auto execute the first HP BIOS update automatically
7.At the command prompt enter ahci.bat and press return to flash the patched BIOS
8.Remove USB stick
9.Restart the machine and enter BIOS with F10 and load defaults. Save and restart.
10.Enter BIOS with F10
11.Go to the Chipset Menu > Southbridge Configuration > SB SATA Configuration (New Menu!)
12.Enable OnChip Sata Channel, OnChip IDE Type to IDE, Sata ID Combined Mode to Disabled and SATA ESP and SATA Power on all PORT to Enabled.

13.While you’re in BIOS, ensure that video memory is set to 32mb to save your ram getting eaten by a video card you aren’t using.
