386 protected mode is a completely different protected mode from 286 protected mode. The 'bug' is not really a bug, but a poor design choice. Apparently Intel did not consider the possibility that people wanted to switch between real and protected mode, so they can run legacy software. They …

Thanks for the tip. I thought as much. I think I may just go with my adlib card and/or maybe my PAS 8bit card then and I do have a Roland MPU-IPC-T card for the MPU to drive all my external MIDI devices. Also, I remember having some strange 8 bit Adlib clone card that may be cool to try, I don't …

I don't think it's even possible, because they both have an OPL2-chip fixed at address 388h, so you'd get a conflict. AFAIK it is possible because the cards just "listen" to the address. So both cards will play at the same time. I'm not sure but it is a benefit of how the original AdLib was …

I'm very excited to hear some actual XG stuff - I love the GM output of the DB50XG but never actually tried any XG material! This post has a file attachment with some XG stuff from Mediatrix: http://www.vogons.org/viewtopic.php?f=46&t=41876#p428862 Also try Fields of Gold by Sting: Fields_Of_Gold. …

No doubt, seems like 30 years after XT clones exploded they're exploding again. (in our small community at least)

@Artex Nice finds! I also have a boxed Gravis Ultrasound ACE. I also have a MAX, but i would really like a boxed classic. The compact MU modules are awesome. Try playing some XG midis with it and you'll see it really shining. It's already good in games but XG stuff is just beautiful.

A multimeter is an essential tool, but i should have got a desoldering station. I'm sure i would have solved his problem already easily. I'm also wondering if a hot air gun would help the best in reheating and reflowing the solder.

All the solder pads were intact, in fact soldering the new caps was quite a breeze and the solder joints were good thanks to the EDSYN flux i use. So i don't know what went wrong. When i first powered the board on after the recapping i got continuos beeping, which in an Award BIOS indicates bad RAM. …

I rather follow how the caps were installed before the recap. Take a look into this picture, motherboard is the same model as mine: http://mail.lipsia.de/~enigma/neu/pics/mainboard_asus_tx97-xe.jpg My caps are installed the exact same way. And yes i actually reheated the solder joints a few hours …

Hi folks, yesterday i set myself to recap my ASUS TX97-XE. It went fine i replaced all VRM caps, some of which were bulged. It was tough to get the old solder to get out but finally i was able to finish the job. So when i power it on i got repeated beeps in an endless loop. This indicates a RAM …

Trodas, do you mind testing the Pentium 90 with the 7.14MHz FSB and see if the crystal mod fixes the keyboard troubles with this setting?

With a nice pizza-box the DTK mobo will be epic , you just need a real IBM CGA IMHO, proper composite is important :D You know what? I've been thinking about it and i'm still tinkering between available choices. The most obvious choice is to use a VGA card which can switch to CGA for some …

Excellent! So glad the mobo is in your hands Carlos :D I am also waiting for a parcel to arrive from the US so I can build my IDEXT card as well - hopefully it will arrive soon. In the meantime I started restoring that Hyundai clone I just got, maybe I use it instead of the Acer one, it has more …
