[Multiple-Monitors & WIN98, Required Hardware]
I found some nice reference material on usenet about Win98 and multi mon setup. I think its quite useful so I'll repost it here:
-------------------------------------------------------------
Multiple Display Support
========================
With multiple-monitors you can use one computer
to control two to nine monitors through a common
desktop. Multiple-monitors increases the size of
your screen, so you can see multiple applications
or windows simultaneously.
Required Hardware for Multiple-Monitors
---------------------------------------
Any combination of the following supported PCI-based
cards can be used with multiple-monitors. Only cards
based on the following chipsets work as secondary cards.
NOTE: You also need to use the specified driver.
- The following drivers are supported by Microsoft and
are included on the Windows 98 CD:
Card Driver
----------------------------------------------------
ATI Mach 64 GX (GX, GXD, VT) ATIM64.drv
ATI Graphics Pro Turbo PCI
ATI Graphics Xpression
ATI WinTurbo
ATI Rage I, II, & II+ ATI_M64.drv
ATI All-In-Wonder
ATI 3D Xpression+ PC2TV
ATI 3D Xpression

ATI Xpert@Work, 4 & 8 MB

Only certain updates work. These are 40, 42, 43,
44, 52, 53, & 54.
NOTE: If the card is at one of these updates, then
Windows 98 will recognize the card as a Trio 64V+,
provided the Microsoft driver is used. If the card
is not at one of these updates, then it is recognized
as a Trio 32/64. Some OEM drivers don't care which
update is present; be sure to note carefully which
Microsoft driver Windows 98 selects when you use
this card.

the Web site at 3dlabs.com
In addition, newer cards and drivers that were not
available when Windows 98 was developed may also
support multiple-monitors. Consult the vendor
documentation or contact the vendor to determine
whether your card and drivers support multiple-monitors.
Setting Up Multiple-Monitors
----------------------------
1. Determine which card you want to use as your
primary card. First make sure that the card
works with multiple-monitors.
2. Insert the card into your motherboard, and then
add your second card. The system BIOS will decide
which card is the primary card. One way to verify
which card is your primary card is to check which
card displays the Windows 98 Startup logo when you
turn on the computer. The card that displays the
Startup logo is the primary card, and the card
that appears to be inactive is the secondary card.
If this is not what you want, reverse the order of
the cards in the PCI slots.
3. Repeat this procedure for each additional card.
Unfortunately, with current system BIOSs, there is
no way to determine which adapter will be the second,
third, or fourth card until the card is actually
used.
4. Start Windows 98. Windows automatically detects
the new cards. When you are prompted, restart
your computer.
5. During Startup, Windows initializes the new secondary
adapter and displays a message indicating the card is
correctly initialized.
6. If the primary card displays in 640x480 and 16
colors, right-click the desktop, click Settings,
click the Colors down arrow, and then select the
256 Colors setting or a higher setting. Click OK,
and then restart your computer.
7. After you log on, right-click desktop, click Properties,
and then click Settings. In the Display area, Windows
lists each video adapter in your system. Find the adapter
you want to use, and click on it.
8. Click the Extend my window desktop onto this monitor
check box, and then click Apply.
Troubleshooting Multiple-Monitor Setup
--------------------------------------
Extend my Windows desktop onto this monitor
option is unavailable:
1. Make sure that the monitor is set to display in
256 colors or higher.
2. Verify that your secondary card is compatible
with multiple-monitors.
3. Make sure you are not using a Windows 3.1
driver for the primary card.
4. Check to see if you are using an ISA, VLB, or
MCA card. Multiple-monitors require PCI or AGP cards
for all display adapters.
5. Check to see whether any third-party display control
panels are installed. Right-click the desktop, and
then click Properties. Look for any tabs that are
related to the video cards in your system. Next,
click Settings, and then click Advanced. You should
see only the General, Adapter, Monitor, Performance,
Color Management, and possibly the ATI Display tabs.
You can usually remove any Display Control Panel
extensions that you find by using the Add/Remove
Programs feature in the Control Panel.
Common Problems:
If your system will not start when you have two video
cards installed or if the second comes up with a "code 12"
in Device Manager, move all the video cards needed to
the slots that are closest to the motherboard when on a
riser card. Some systems only support display adapter
cards in the first one or two slots closest to the
motherboard.
If you experience one of the following problems, disable
your on-board Rage II. This device cannot be used as one
of your multiple-monitor display adapters.
- Your on-board ATI Rage II displays vertical green
bands when you install the secondary card.
- Your system locks up during Startup, and the Automatic
Skip Driver (ASD) reports that My system died while
initializing a video ROM.
- Your IBM Aptiva locks up during Startup after detecting
the secondary, loading the drivers, and rebooting.
- Nothing happens when you click the Extend my Windows
desktop onto this monitor check box.
If a yellow exclamation point appears beside one of your
video cards in Device Manager and if it indicates the region
of memory that the video card uses is in use, try one of
the following:
- On some laptops, you can specify where the region
of memory used by the video card is located in the
system BIOS. Set this to C000-CFFF or to the largest
range possible that begins with C000.
- Remove EMM386.EXE
- Type the following under the [386enh] section of
system.ini:
Emmexclude C000-CFFF
If your system locks up after installing the secondary
card when you add a STB Workstation two-adapter card, then
the video cards in this system are configured incorrectly
by the system BIOS. As a result, it destabilizes the entire
system. Your particular system probably cannot use video
cards that are behind PCI-PCI bridges.
If your card is listed in the supported card section, but
Device Manager indicates that your card does not work with
Multiple Display Support, then make sure that you are using
the right driver, as listed at the beginning of this document.
If Device Manager indicates that My primary video card
cannot be disabled, your card is not supported in this
configuration for multiple-monitor.
If you experience one of the following problems, then your
display driver is not compatible with multi-monitor. Contact
your vendor for an updated driver.
- If your screen goes black during Startup or your system
hangs and the Windows bootlog option indicates that the
problem occurred in GDI.
- A message appears on your screen indicating that a fatal
exception has occurred in GDI.
