[computer-tech-support: 7677] Promise EIDEMAX

I recently bought a used Promise EIDEMAX ISA card to support a 3 GB
hard disk in my old 486DX-33 computer. I did not receive a User's
Manual, so I am having to guess how to make it work. So far, I have
discovered that if I set the CMOS hard drive info as "Not
Installed" (aka Type 0), or as Type 1, the EIDEMAX will recognize and
use the full capacity of the hard disk. If I set the CMOS hard drive
info as User Defined Type 47, 6296 cylinders x 16 heads x 63 sectors
(the true CHS parameters of the disk), the EIDEMAX will use only the
first 1024 cylinders, and thus be limited to 504 MB, just like the
motherboard BIOS.

Can anyone tell me what are the "optimum" jumper settings for the
EIDEMAX card, and whether there are better ways to set the hard drive
CMOS settings?

Currently, the IRQ jumper is set for IRQ 15. Should it be IRQ 14?
The Secondary/Primary jumper is set for Secondary. Should it be
Primary?

I have found a description of the jumper settings (at STASON.ORG), but
the STASON site gives no info on how the jumper settings should be
set.

I'm hoping that someone has used this card in the past, and can recall
the proper way to set it up.
