X48 - Host Not Responding

[Nelson McSwain]

When I try to boot up my X48 I get an error message that says Host not responding, please see owners manual. Well I'm not able to find anything about the issue in the manual. After several tries the recorder starts but this is an issue that will make the recorder hard to sell and that's what I'm trying to do. Any help?

Try reloading the BIOS settings. Tascam has them and the procedure.

Note - Firstly, if you haven't done it, change out the battery (CR2032) on the motherboard - You also need a PS2 keyboard (not USB), otherwise you won't be able to get into the BIOS and check it / reset it.

The 'sometimes it does, sometimes it doesn't' is also consistent with potentially the power supply caps being bad - known problem on some units - TASCAM got a bad batch which ended up in the X48's - this will also cause the same response.

Also there are other threads in this forum on this subject that will lead you to the BIOS settings download 'X48 bios set up' - links / downloads on pages 1 and 2

Good Luck if you haven't fixed it yet.

HOST NOT RESPONDING
Just like TASCAM do !!!

The one that TASCAM does not provide to users of his machine!

When the battery is removed all BiOS data is "erased".

Super important because indicates where the Mothercard must connect, USB keyboard possible or not , but to be sure always use a PS2 keyboard to do all that stuff BiOS

- FW IEE1394 possible for external HDD? And plenty of other things,
But it is the Battery that keeps all this data

Your BiOS allows you to configure the operation of your components (clock speed, timings, etc etc). The problem is that the Chip the BIOS is on, can only be READ, so changes made are stored on another Chip called CMOS for Complementary Metal-Oxide Semiconductor, I expect battery powered.

As a precaution, after changing the battery, I first unplug the X48 if I had left it plugged in.
But may be if the battery is not totally out of duty you can change it with the X 48 ON to save the Bios programming but with Full precautions , I didn't try it, don't know, and I deny any responsability about that !!


Sometimes we are lucky, it restarts normally, but in general the X48 no longer opens on a project, and displays lots of windows , with screened in front of the device


"HOST NOT RESPONDING"


And if you have a Boot CD inside, thinking it's a problem of Hard internal drive, it will do the whole process, and when you want to partition and format the internal hard drive, at the end of the process it will tell you


"An error occured while formatting your OS drive, (with usual Bla Bla stuf about "Technical Support"...which is unreachable !)


Before being saved by this site, and the Posts of HelllvisPreley and others, I spent whole days trying to find the solution for this Big mess…Save my data on a computer, or other hard drive, try to reformat everything ,etc .. I'll spare you the details!

PROGRAMMING THE BiOS

Pitfall No. 1
You have to connect with a PS2 Keyboard…. it seems!
(The USB keyboard connection on an old X48 is also programmed in the BiOS!)

The first element to access the BiOS programming is;
As soon as the X48 turns on, and see the Display screen,
you must PRESS THE SUPPR KEY

Here is Pitfall N° 2 : Not the DELETE key with the arrow to the left which is used in Word for example to erase, but the SUPPR KEY
(you need a keyboard where it really appears, somewhere at the top right)

And there we finally have access to the setting window for all the elements of the BiOS
At each sub-window, exit by ESCAPE, and finally exit and save by F10 and then
the classic X 48 Project window reappears!! MIRACLE !!

LIST OF SETTINGS TO MAKE IN THE BIOS

The way to change values, to move, etc.; are marked at the bottom of the window,
even me, I understood !

1/ Go to the line "I will smart setting" / ENTER

Line : Change on-chip serial ATA set to ( ENABLED )

Line : Serial ATA Port0 mode, set to ( SATA0 Master )

Line : On Board 1394 line set on ( ENABLED )

ESCAPE


2/ Go to the line : "Cmos features" / ENTER


Set date and time

Line : Drive A, set to "NONE"

Line : Halt On, set to "No Errors"

ESCAPE


3/ Go to the Line : "Advanced BiOS Features" / ENTER


Line : First Boot device set to (CD-ROM)

Line : Third Boot Device set to (DISABLED)

Line Boot Other Device set to (DISABLED)

ESCAPE


4/ Go to the Line "Integrated Peripherals" / ENTER

then Line "Onboard Device" / ENTER


Line : USB Keyboard Support set to ( ENABLED )

Line : USB Mouse support, set to ( ENABLED )

ESCAPE

(Then, still in Integrated Peripherals, go to ..

Line : Super IO DEVICE / ENTER


Line : Onboard fdc Controller set to (DISABLED)

Line : PWRON After Pwr-fail to, put on (Former-Sts)

ESCAPE

And eventually, recheck everything,

Otherwise…., F10 for Save, and there it displays a Y for yes ,
and / ENTER and it's gone!
Everything is saved, there will be a little time, then it's MAGIC
we will FINALLY see the Projects window reappear with its Tracks!!

I did not take care of the Supervisor and User Password lines,
and the lines that I do not quote in this manual, I left them
as they were
