Emax

The problem below has probably been posted here before, but the 
search engine on the yahoo groups seems not to scan older messages 
anymore, so I thought I'm "allowed" give it another try:

I just connected a hard disk to my Emax Plus Rack. Except for the 
floppy drive, no other hard drive is connected to the Emax. The SCSI 
ID of the HD is set to 0.
The problem is: the Emax only wants to boot from the floppy. Once 
this is done, it recognizes the HD on SCSI ID O and I can load/unload 
banks from it. The HD also contains the Plus operating system: it has 
been formatted by the Emax and I performed an additional "copy 
software" just to be sure...

Now I read about this "cheat" of the floppy connector on the 
motherboard (jumper between pins 25 and 26).
But that's mainly used for replacing the floppy drive by an internal 
ZIP drive and making sure that the Emax still thinks a floppy drive 
is connected. That's not what I want.

Bottom line: I don't understand this boot issue with the Emax. In the 
original documentation of Emu, it seemed perfectly possible to have 
an Emax with both an internal HD and a floppy drive. When booting, 
the Emax should first check the floppy drive; if no floppy disk is 
found, the Emax should boot from the HD on SCSI ID 0.
It doesn't do that on mine, it doesn't even check the SCSI chain, it 
immediately asks to insert a disk.

So what do you think I'm doing wrong ?

Thanks

Esynthesist-

After all you have done to help this group as you have, I think I speak for
most of us, if not all, when I say your posts are welcome, whatever they may
be.....

I noticed the inability to scan earlier posts myself recently.

I dunno what may be wrong. I am not sure.

.....termination pwr jumper missing for the drive or missing termination
resistors?
....the drive is on the last connector of the cable....correct?
You say no external HD is hooked, do you have an external Zip hooked????

Can you clarify exactly the scsi chain-

for example:
emax board ------   scsi cable------  last connector of cable ------ HD
HD settings- which HD and what jumpers are there....
Confirm value of the termination resistors- they should be 220/330ohm.

My Compact Flash drives are set as ID 0 on my Rack and keyboard. I have slim
floppy on both units.
They work as you describe  in the "bottom line" section of your post-
If floppy is present, boot from it, if no floppy, boot from CF/HD......

I am using SE Plus 1.0 OS.

Regards,
Ted

As with all computer equipment there can be low level problems that
ultimately can be traced back to the button battery as in a CMOS/BIOS.
 Have you ever replaced the internal battery?

EASY SOLUTION:  On an Emax II make sure your SCSI boot ID is right,
which is MASTER 9,6.  Validate beforehand with DRIVE SELECT and the
DATA slider what SCSI ID is your HDD.

BACKGROUND:

I own an Emax II 2212 and have an external SCSI drive connected with
an ACTIVE TERMINATOR on the 'out/chain' connector of the box, in my
case, the top connector, the bottom has the cable.  I booted with the
floppy and then followed the EMAX II manual for formatting a HD with
the OS included.  It is a Connor 540mb so it took something like
nearly two hours to format by the Emax.  Everything went well, etc.
and through 'DRIVE SELECT' and the DATA slider the settings I was able
to make sure what the true SCSI ID of the drive was, and through
MASTER 9,6 to make the SCSI BOOT ID the same value.  In my case the
first boot ID was the SCSI 1, as an EMAX II considers the floppy as
SCSI 0.  As long as I had it plugged into power it worked fine, even
being off for days at a time.  Once I disassembled the setup and moved
it to another location, it did not want to recognize the SCSI device
first and asked for the floppy.

I was puzzled so went back into DRIVE SELECT and the Data slider and
verified the location of the device on the chain, it was being seen
fine.  Then I went into MASTER 9,6 and found that it had reverted back
to SCSI 0 which is the floppy. I just assumed that it got 'knocked
out' somehow just like needing to calibrate the sliders from time to
time, they just fall out for whatever reason.

I don't know how different the Emax Plus rack model is from an Emax
II, but here are the steps as it pertains to my situation:

0. Verify you have an active terminator on your SCSI device!  Mine has
a LED so I know it is working as it should.
1.  Make sure the external HD is well powered up before turning on the
Emax. I usually wait 10-15 seconds.
2.  Turn on the Emax and watch the display immediately.  This can give
you alot of information in about one half second of time.  As you
said, it is not searching the chain, so it is probably going straight
for the floppy.
3.  Go ahead and insert the floppy disk when prompted, let it boot
into the OS and then follow the instructions above, namely make sure
you know what the Emax is seeing your external HD as through DRIVE
SELECT and the data slider, then go into MASTER 9,6 to make sure it is
choosing that number to boot from over the floppy, which usually takes
up SCSI ID 0.

I don't know why mine fell out and had to be reset like that, but I am
assuming it needs a new clock battery (as well as a backlight and B key!)

GOOD LUCK!

OK, here's my setup:

- The Emax Plus contains the newest PC333 motherboard, so it has 
native SCSI support. 
- It only has a floppy drive, no internal HD.
- Since it didn't have an external SCSI port originally, I added it a 
while ago. This port is connected to the CN2 50-pin motherboard 
connector, which is intended to be used for the internal hard drive. 
The CN9 25-pin connector, which is intended to be used for the 
external port is not used.
- I have put an internal IBM WDS380S hard drive (80 MB) into an 
external HD box which was used with one of my Mac computers. The case 
is an original Mac 540MB case, but the original Quantum drive is 
dead, so I replaced it by the IBM one. Anyway: towards the Emax, this 
HD behaves like an external HD, connected to the external SCSI port 
of the Emax...
- I didn't set any jumpers on this drive because to select SCSI ID 0 
no jumper should be set on the ID0/1/2 pins, so that's OK.
- The external port of the Emax is internally connected to the last 
connector of the ribbon cable; the previous 2 connectors of that 
cable are not used.
- The SCSI chain is terminated by the Mac TI03T external terminator 
which is put onto the second SCSI port of the external case, and 
which was the original terminator device which joined the Mac 
external HD.


What I did in the meantime:
- I replaced the floppy drive by the one of my Emax SE keyboard --> 
same problem: no HD boot.
- I disconnected the floppy drive ribbon cable from the motherboard --
> emax crashes at boot time
- I connected a ZIP drive (SCSI ID 6) to the second SCSI port of the 
external case, and terminated the ZIP drive, so I have a HD on scsi 0 
and a terminated ZIP on scsi 6 --> same problem: no HD boot.
- I connected the very same HD to my Emax-II (again in the external 
box), I changed the SCSI ID to 1 --> Emax II is able to boot from the 
this hard drive.

What I still could try to do is to hook the drive directly to the 
motherboard (without using the external port), but I don't know how 
to terminate this drive. 

Last important (odd) remark:
Once the Emax has booted from the floppy disk, it doesn't need this 
disk anymore ! So when the Emax has to load another part of the OS 
(when I press a module button), it loads this OS module from the hard 
disk instead of the floppy disk !!

I don't understand this machine :-)

Thanks for the detailed information.
But the Emax-I is quite different from the Emax-II in the field of 
SCSI behaviour. The Emax OS also doesn't have a "set SCSI ID" option 
like the Emax-II does.
And... as far as I know there's no battery in an Emax :-)

Small update:

I just remembered that my Emax Plus is a prototype one (serial 002).
A long time ago I posted a message on this group about the strange 
chipset on this Emax motherboard (see message 3382).
The SCSI EPROM chip is not the IP355 as one would expect, but it is 
an (older) IP349C. It is however installed on the 28 pin socket 
already. On the other side of the board, a piggyback board for IP349 
has been installed.

Questions:
- is it possible that the "boot sequence" is controlled by this chip ?
- I received the SCSI upgrade kit from Ted, so I have a new IP355-
like 28-pin EPROM chip available (my Emax SE has not been upgraded 
yet with this kit, that's why :-). Would it be smart to replace the 
IP349C chip by the new one, just to test if this solves the boot 
problem ? I have to say I'm a little bit afraid, because there is 
that mysterious piggyback board called "IP349 piggyback". I have no 
idea what the relation is between this small board and that chip...

I hadn't heard of this issue.

It should do just as you say- check floppy, when not found boot HD.

What version EPROM is in that unit?

The only other things I could think of is:
 if Pin 18 solder connection was broken, as that is the ACK signal.
And on boot I would think if the CPU didn't get an ACK back, then perhaps it wouldn't think there was a drive there�.


or perhaps termination issue.

just a thought�

dont put a floppy disk in the floppy drive if you do put a bootable disk it will always boot from floppy first

I have the same problem with my rack unit.
It's your floppy drive, it is on it's way out.
If I take the HD out of the rack, and put it in my keyboard, it will boot from the HD, but if I put the floppy from the rack into the keyboard, the keyboard will not boot from the hard drive.
If I jumper pins 25/26, then the rack will boot from the HD.

I have an Emax II but,

Have you checked that the operating system is copied on the harddrive?
Emax setting acknowleged it must boot from HD ID...?

With and Emax II I know that sometimes the HD ID chain of 0 must be placed higher (example id 7) in order to make it bootable. The HD ready signal can sometimes be slower than the access time of the Emax II in order to find it on "time". Could this also count for an Emax I?

Another possibility is to remove gently the scanner cpu en reseat it in firmly again.

Hopes this will help you.

Kind regards,
Frank

emaxII needs to have the hd or cf drive as boot scsi id1 and not 0

like on the emax 1 emax 1 needs scsi id 0 for it to boot from

i had a customer take out his cf drive out of the emax 1 and put it into the emax 2 saying it would not work

but when he put it back into the emax1 it would boot

ted came back with a message saying it needed to be on scsi id1 for emax 2 to boot from

so customer put it to id1 and then it booted from the cf drive in the emaxII
