Many people ask me If I would consider selling my 2805-S402. Short answer is no, long answer is there is no availability. I have not seen another, so I might not get a chance to ever own another. It is hard enough to find a good 2805 series, it seems impossible to find the one I got that has the geforce 2 go.

However I will give a guide here that should work on getting the 2805 series sound working in pure DOS and 98 properly that should apply to all the other models.

1. To go into BIOS press ESC and it will prompt you to hit F1.
2. 1st page configure parallel port as std-bi direct
3. Press page up or down to go into 2nd bios screen. You want to change Config to all devices instead of by os.
4. For parallel port select not used.

Windows Config
5. Install windows 98
6. You want to use the VXD drivers for windows I will link to to.
7. Go to device manager select the parallel port and manually change the resources. That means uncheck automatic settings.
go through the basic configurations until you find the setting that doesn't use and IRQ. On mine that is setting 003. Then Save that and I went ahead and disabled the port anyways.
8. for sound a video game controller you want to click on the legacy sound system, again you want to manually set the resources. Try Basic configuration 2. Change to IRQ7 DMA 1 io 220-220f, 388-038f, 330-0331f etc These are the like the default legacy values.

For Dos.
1. You have to use the modified 810/815 driver I'll link.
2. The SET Blaster Parameters. are SET BLASTER=A220 I7 D1 T4
3. I already configured this in the driver I am going to link here. But if you use the one off Phils computer page you need to change somethings to get it to work.
4. If you use some other driver than the one for here. Be advised that the one from phils has the wrong environmental variables set up in the batch file and you need to change that.
5. To configure you go "YMFIRQ 11" without quotes at the command prompt.
6. Type SETUPDS Change it to S-IRQ and then you can change it to I7 220 D1 ETC. With the driver I will link it should already be setup for you. Then save.
7. Then to run the driver you type Loadtsr at the command prompt that's all.

Unpack Dos driver to C:\Yamaha It should just be Yamaha and all the files not Yamaha\Yamaha or anything else.

Fresh DS.INI if you run into any trouble. Use this only if its not letting you modify SETUPDS and save it.

It's working on my 401, thanks! Never thought that laptop can be near Roland devices.

Sir, do you know if this laptop supports native dos sound? Satellite 2805-S503

Pure crap !
It's like a YMF743. It's just an AC97 soundchip. Everything about Soundblaster and legacy sound has been discarded.
Its meaningless to try to use this to play DOS games in native DOS.

Yamaha has made this to try to match costless solutions. The Toshiba SP4600 has the same soundshit.

Toshiba 2805-S202 support native Dos sound as well, but video chip is S3 Savage IX M7.

CPUSPD (Dos utility to throttle CPU) use at own risk of course. It throttles the FSB to slow CPU. So at 1/8 its like 12mhz FSB x 8 multiplier which get you to like 100 mhz . You should be able to slow laptop down below 486 speeds and with L2 cache disabled. you might be able to hit 486 speed with like 4/8 L2 off.
options are 1/8 - 2/8 -3/8- 4/8- 5/8- 6/8-/ 7/8- 8/8 l2 on l1 on - L2 off l1 on - l2off l1off- at any multiplier.

I recommend not running powermizer on full. If you want to use less power and less heat adjust lower. Obviously the oem driver always runs it at full, so its not a issue either way.

Thanks! Saved to my pc and made a mirror (with some small titles adjustments): https://www.dropbox.com/sh/qolj1fmwncdmo7a/AA … ewjx6fzOca?dl=0

Few questions:
Why not using GeForce on full power? I don't think someone bothers with battery life today.
Why there are no official video drivers from the support page? It has known issues?
How cooling is done for the Geforce 2go model? Do you have a photo of the internals?

we can link to official drivers, but there's no need to upload them, since the laptop is supported elsewhere on official page. The official video driver is fine but it's version 7.76 or something. Very old driver. 12.41s work fine as well, anyone is free to modify 12.41s themselves if they want. 14.10 Felt very good on the laptop, I tried lots of drivers and its what I settled with.

Idk what is up with the cooling of the geforce2 go. Assume its fine for these laptops to still be functioning 20 years later. I don't think it it's a issue.

7.76 is very limited. it doesn't have many features, and it doesn't work with every game.

Do you notice horrible “farting sound” when volume is on maximum? At first I thought that my speakers are broken, but looks like they are okay. Seems like system allows sound higher then it should be.

It allow higher sound than it should be. Just adjust the volume. That being said its a know issue with all XGs as mentioned in the XG thread. Yamaha YMF7x4 Guide

2.2. Crackling
  
  Crackling may be caused by too high maximum volume. Sometimes it's because driver allows to set the volume too high, when it was taken from another card. With VxD drivers you may fix it in registry: HKEY_LOCAL_MACHINE\Software\YAMAHA\Driver\YMF724\VolumeMax, or by YMF7x4Utilities.

Custom OEMINFO. You can mod the ini to match specific type. Place both file in windows system folder.

Tested the Power YMF 2.0.1. From phils site it worked good from my testing. https://www.philscomputerlab.com/yamaha-ymf74 … sound-card.html
Program allows you to load midi banks on the XG and more control over it.
The Extended Bank for Power YMF. upgrades the wavetable to 4.61 MB and it increased the quality noticeably. Tested that with heros of might and magic II and FFVII setup.
