Greetings, all: Yeah, I had another lovely chat with the fine product support fellows in Montebello, CA and I now have received a detailed .pdf download on the bios setup issue.
This isn't some reprint from the service manual, no way - it's a HANDWRITTEN set of instructions from Ed (the bench tech), with subsequent screen shots of the actual settings desired. Because the order in which bios is reset is important, the screen shots are labeled with numbers, and the notes prompt the actions required.
I read the whole thing, and it does seem to match what we did on the phone. If anyone trying to do this gets confused, just calm down and start over - you can't blow the thing up if you hit the wrong key. I find re-reading the words often helps; sometimes it doesn't correctly register in the brain-pan the first time....Cheerio!

X48 Bios Set Up.pdf

Hello and sorry to put you to work after all this time.
I diligently read your advice and indeed my breakdown corresponds to the problem you describe, so I downloaded your precious instructions for performing a Reset of the BiOS.
But being very far from knowing in pure computing and even less on Windows, I have 3 questions left:
1/ I read somewhere that on windows computers, with the machine off, if you remove the battery for at least 15 seconds, it reset the BiOS autommatically ?
Is there a risk in doing this?
2 / In step 5 you indicate to enter or define a password ?
because the password for my X 48 I do not have one !
Or the process F10 and to Clic on the letter Y on keyboard will work anyway,
3/ I don't understand your formula at the beginning,
"Go to I Will Smart Setting", is that really marked somewhere when you turn on the machine??
The following is the explanation of my problem, I put it for other members to compare, but I believe your BiOS Reset is the solution, and thanks again.
And I confirm, I buy a second-hand X 48 it works, I say to myself hey it's old, I'm going to change the battery, I turn off, I change the battery, and I turn it back on, doesn't work anymore and no way to format my drive after the full proces from my boot CD!
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
Well I know that the X 48 is no longer produced and that many of you no longer use it but for me it remains very valuable for lots of uses.
So I keep a little hope if someone has experienced the same kind of problem as me:
Everything works perfectly everywhere, the hard disk too, I checked, everything was working, but suddenly, and that probably, finally I suppose, following the change of the battery which generates the date of the day,
No longer possible to access the opening of the basic project window and therefore no longer access to anything.
So I tried again starting from the OS of the original CD, as well as more recent OS 1.2
loaded from the Tascam Europe site.
I know the procedure perfectly except that each time I arrive, at the end of the attempt to reinstall the OS, on the window:
"An error occured while formatting your OS Drive"
"Sorry the installation Failed"
I know the machine, Sata connections etc, very well inside out, and on one of my X48's I even changed the internal hard drive to a bigger one with success, so I tried absolutely everything.
And of course first of all I replaced the internal hard drive but that was not the problem,
and even also to preformat it externally to NTFS, but that wasn't the problem either!
The feeling I have is that everything works "hardware" perfectly up to the motherboard but there is a bug, a computer impossibility or a shortcut, or a key combination, or an operation, a thing to know, I don't know, somewhere to make it work!!
So in case you faced the same problem and solved it,
I'll take it .
THANK YOU THANK YOU for having reading me until there

, So do not waste too much time on it, do not feel "obliged", and maybe another member can give me advice to that purpose !
