[computer-tech-support: 7701] Re: Promise EIDEMAX

First off, since setting the correct CHS parameters for disk type has
a problem
this then seems to indicate that the major problem you have is with
your BIOS
(not the BIOS in the EIDEMAX). ALso, since the EIDEMAX does have an
IDE
interface - did you try connecting the drive to it? According to the
doc at
stason.org the interface is enabled by default and it is the primary
IDE
controller plus the on-board BIOS is enabled. Next, since the legacy
MF card would have it's IDE set to IRQ 15 you should change the
EIDEMAX
to IRQ 14.

Now, as for googling... I found over 1300 references - for
"promise eidemax" (though a very good portion of them are
for the EIDEMAX II). And, which revision of the EIDEMAX do you
have? Original, or REV B? (there are two docs on stason.org;
1 for each rev.) The Rev A can have the on-board BIOS disabled,
the REV B can't.

And, in reference to hard disk limitations in DOS, etc, see:
http://www.computing.net/answers/dos/limitation-in-hard-disk-drive-size-in-dos/2097.html
It has a very good description on limitations within the software and
BIOS and may
explain what is going on with your system. And, within your system,
it is 0, or 1 which is the 'auto-type' setting, unless there is a
specific
one that says 'auto'. You may have to upgrade your systems BIOS
(if there is an upgrade)

I have not been able to locate a 'user' manual for the EIDEMAX (only
for the II)

Now, you need to understand that the EIDEMAX was originally meant as
a primary controller (as evidenced by the REV A default jumpers), or
as
a secondary controller. You MUST connect the drives it is to control
to it which is what you are NOT doing. You are still using your
original IDE controller as evidenced by the cable from the drive!
