X. Troubleshooting / FAQ
This chapter addresses common questions to solve possible problems and avoid
conflict with other PC hardware or specific system configurations.
Q: Can I use the card with an AMD Athlon / Duron / Thunderbird CPU? Will it work
with a VIA Cyrix CPU?
A: Yes, of course! There are no compatibility issues with microprocessors. Please also check
the following question about VIA chipsets, as many mainboards for AMD and VIA CPUs are
based on VIA chipsets.
Q: What about VIA chipsets? Can I use my VIA chipset based mainboard with the card?
A: Yes, you can use VIA based systems with the DSP24 series of cards. Unlike with some other
chipsets, the configuration in this case is more 'sensitive' and the system needs to be properly
configured to avoid possible trouble:
Please make sure the DSP24 PCI card gets a unique and unshared IRQ. Secondly, a recent
version of the VIA 4-in-1 driver (we recommend at least v4.31) and the VIA USB Filter driver
must be installed (check http://www.via.com.tw/ or the website of your mainboard
manufacturer). If you are using Windows 98SE with USB enabled, Microsoft's UHCD Update
should be used as well (do a search for 'uhcd.sys' on Microsoft's Knowledge Base).
Please check if there is an update for the BIOS of your mainboard ... if so, please download and
use it.
On mainboards with the KT133 and KT133A chipset, you must use high quality 133MHz
memory modules only. Also check the correspsonding setting in your BIOS (it should be set to
133MHz) and make sure the memory timing is not set to an incorrect (e.g. too low) value.
Set PCI DELAY TRANSACTION in your BIOS to DISABLED. Then, set PCI DEVICE
LATENCY TIMER to a value of 32 or lower. PCI MASTER READ CACHING should be set
to DISABLED as well (could cause performance problems, but because of the VIA
southbridge bug, this setting is required).
Last but not least, we recommend to disable all power managment related functions.

Q: Is it possible to install this card in a system with onboard-sound or another
soundcard?
A: Usually yes. As long as the other soundchip does not use a Envy24 / ICE1712, there should
be no problems. You should make sure that both devices do not share their IRQ.
Q: How many available IRQs do I need to use the card?
A: Exactly one. It should be unshared if possible, because the DSP24 is a busmaster device ...
otherwise you might get performance problems. It does not matter which IRQ number has been
assigned to the card.
