Ultima VII is without doubt one of the greatest CRPG’s and perhaps one of the best RPG games ever made. It is also without doubt one of the hardest games to get running correctly. In this article we are going to take a look at building a PC specifically for the purpose of playing one game, Ultima VII and Ultima VII part II, Serpent Isle

Before I get into the meat and potatoes of this article I do want to point out there are various patches and fixes to allow Ultima VII to play on a Windows 9X computer, there are also other methods that allow one to play the game on a machine that normally would not play U7 optimally such as utilities or jumper tricks to slow down faster PC’s or simply using a boot disk to configure things correctly. That is not the reason or focus of this article. In this article we are building a PC specifically for the sole purpose to play U7 as optimized as we can using “mostly” period hardware in a DOS environment without the aid of patches or boot disks.

The first question one might ask is “Why would I want to play Ultima VII”? The answer to this question I actually answered in the first paragraph. U7 is widely considered one of the greatest RPG games of all time so if you are a RPG lover you owe it to yourself to play this game. The second question one would likely ask is “Why is it so hard to get this game running correctly, or for that matter running at all”? That is the question we will be looking at below as well as how to put together a PC that addresses these issues.

There are basically two major reasons and one minor reason this game was and still is so hard to get running. I’ve read stories of people buying this game back on release and having to return it due to not being able how to figure out how to make it run. We’ll start with the more minor issue first and then work our way up to the major roadblock to getting this game to run properly.

1 ) Hard drives usage – Ultima VII accesses the hard dive A LOT. This can result in continuous stuttering or pauses as the screen scrolls. This though is the most minor of issues when hoping to play U7 on real hardware. The simplest advise I have for this is find the fastest hard drive and hard drive controller you can find for your build and use that. I went with a VLB controller paired with a none era correct compact flash card which I think works very well as a solution.

2) CPU speed sensitivity –  Ultima VII is one of those games that require a vary specific CPU speed or things will either play to slowly or to fast. You can play the game on a 40mhz 386 or early 486 but the game just bogs down. On a 66mhz 486DX2 or above the game just plays way to fast.  a 33mhz 486 is largely considered the “official” recommended CPU speed but I would say the U7 Goldilocks range is between a 33mhz 486 and a 50mhz 486DX2. On a 50mhz DX the game just runs a little to fast and on a 66mhz DX2 it becomes almost unplayable especially if your chasing something on screen such as a monster. Users of 66mhz DX2’s can play with jumpers on the motherboard and set your FSB to 20mhz to simulate a 40mhz DX2 (which never existed as an actual 486 CPU) which plays the game pretty optimally. Those trying to slow down their machine by using programs to disable internal cache may find a nasty surprise as the game re-initializes cache if it is disabled.

3) Memory management – The greatest hurdle in getting U7 to work at all is the custom memory manager known as the Voodoo Memory Manager that the game REQUIRES to work. This manager is incompatible with just about all expanded memory managers such as EMM386. On top of this the game requires a fairly large amount of conventional memory, as much as 585kb. This is the core of the problem. In normal use a user would use a program such as EMM386 or QEMM to move essential drivers into upper memory thus freeing up conventional memory for games. The requirement to use the custom Voodoo manager thus prevents this and in turn you can’t free up enough conventional memory for the game since it’s eaten up by drivers for various required things such as CD-ROM drivers, mouse drivers, SMARTDRV, ect… This requires users to either use a boot disk with a minimal setup  or hand pick the smallest compatible drivers that can be found and trim the system down to the required basics.

Here is a look at my “Ultimate Ultima VII PC” and how I set things up to play U7 without the need for a boot disk or any slowdown utilities.




I came across this machine at a local swap meet and thought the compact case would be perfect for this U7 build I had in my head.

The motherboard I’m using is a version of the FIC 486-GVT U2, and Is the same board I have used previously in my 50mhz DX machine. I’m using 24MB of RAM (U7 only requires 4MB) as well as 256k of L2 cache.


Before I get into the software side of things and show you how I’ve set up DOS to have enough conventional memory while retaining the needed drivers and using the custom Voodoo Memory Management system U7 requires lets go over the hardware.

CPU – Initially I went with the generally recommended 33mhz 486DX but after some further research I concluded the optimal CPU for my tastes is the AMD 486DX-40 running on a 40mhz front side bus. I decided on this CPU over the 33mhz because I felt that later in the game when there are multiple enemies and things happening on screen the extra CPU power could really come in handy in preventing things from bogging down to much.


Video – For video I went with my old VLB Diamond Speedster Pro based on the Cirrus Logic GD5428 chip. I have used this card in the past and overall it is a fast and compatible video card for DOS.


The combination of the 40mhz DX CPU and fast video may result in the game running marginally fast in areas such as the city but nothing that ruins the game. To be honest if it is running slightly faster then it should in these areas I’m not noticing it to any great degree.

Also please note there seems to be some sort of incompatibility with cards using the ET4000 chipset and Ultima VII. The issue seems to be a shimmering effect or what I see as sort of “VCR tracking lines” appearing at the top of the screen. I have confirmed this is an issue effecting several ET4000 cards by testing multiple cards from different manufacturers and also talking to others that share the same issue.

Here is a video showing the effect when U7 is played with an ISA ET4000 based card.

Audio – Ultima 7 offers the option to use the MT-32 for music as well as FM. Obviously the Roland MT-32 midi module offers superior quality in music and so that is the direction I took my machine. I didn’t want to spend extra money on a Roland midi interface card but thankfully U7 does not require intelligent mode to play its midi via the joystick port on a standard sound card. Knowing this I went a slightly unexpected route and went with a sound blaster clone card, the Audio Excel PNP16.


I decided to go with a clone card because the Sound Blaster Pro cards do not support midi via the joystick port and Sound Blaster 16 cards are prone to the “hanging midi bug”. A careful observer may notice the complete lack of a real OPL FM chip on this card. For me this wasn’t an issues as I do not plan to use FM and only need this card for the MIDI interface capabilities and for digital sound effects. If you are planning on using the FM track for music as opposed to a Roland MT-32 I would recommend a Sound Blaster Pro 2.0 or Sound Blaster 16 with a real OPL FM chip.

Hard Drive – As I mentioned earlier U7 thrashes most hard drives so I strongly recommend getting the fastest hard drive and controller you can. I decided to go for a VLB HDD controller as well as a era incorrect 512mb compact flash card to use as a hard drive.


The hard drive controller I’m using the the VLB  DTC 2278 enhanced IDE controller card. There are certainly faster controllers out there but not wanting to spend money on expensive and hard to find controllers with on board cache RAM I felt this card was quite capable.

For the hard drive itself I went with a Sandisk 512mb compact flash card on a IDE to CF adapter. I also housed this card in a removable HDD caddy so If I ever wanted to use the machine for something other then Ultima VII and did not want to mess around with my configuration I could simply and easily swap hard drives.



So now that we’ve taken a look at the hardware lets take a look on how to setup DOS to get U7 running.

getting enough conventional memory to run Ultima VII and Serpent isle (which requires even more memory then part VII) without being able to utilize upper memory was a bit of a chore. Firstly you only want to load drivers that are needed for the game so this would include CD-ROM drivers, mouse drivers and sound card drivers if required depending on the card your using. SMARTDRV is also recommended to help with speeding up hard drive access. This means you don’t want to be loading any drivers that are not necessary to the games so nothing for example like drivers for a ZIP drive need to be loaded.

Next you need to search for the smallest sized drivers you can and hope they are compatible with whatever motherboard or drives your using. Some of these nonstandard drivers may have compatibility problems with other games but for the Ultima VII PC we only care if they work with U7. here is a look at my memory usage on my U7 PC and the drivers I’m using.


This setup gives me more then enough conventional and XMS memory for Ultima VII and Serpent Isle. Here are some of the recommended drivers I used.

Mouse – CTMOUSE, the most compatible and smallest DOS mouse drivers out there, I actually use these drivers as standard for my DOS PC’s.

CD-ROM – I used VIDE-CDD drivers for my CD-ROM drive and SHSUCDX as a substitute for MSCDEX. these both take up significantly less space then my usual GSCDROM and MSCDEX combo which combined can eat a whopping 57k of memory compared to 11k of the  VIDE-CDD and SHSUCDX combo. This combo may very well have inferior overall compatibility but remember, for this project we are only concerned with U7. One side effect of using VIDE-CDD is on boot up I get a brief speaker beep and illegal operation error yet the CD drive seems to detect and operate flawlessly. VIDE-CDD & SHSUCDX –

Everything else I’m running is standard with AEMIX being for my sound card.

If your having trouble finding drivers that work and that are small enough you can possibly get away with disabling SMARTDRV if your using a more modern HDD or a compact flash drive. SMARTDRV is primarily most useful in boosting performance of older more period correct hard drives.

Finally a look at my Autoexec.bat and Config.sys files.



Ignore the GSCDROM line I have REMed. I was initially using them for my CD-ROM drive but switched over to the VIDE-CDD drivers in order to get Serpent Isle to run.

In conclusion I hope this information helps anyone out there looking to play Ultima VII on real hardware and helps alleviate some of the frustration associated with putting together such a build.
