Need to reset ESCD on every boot

Hi,

I have a Tyan trinity KT v 1.06 MOBO with Award Modular BIOS v6.00PG.

It has an Athlon 1200 MHz CPU.

I know it's old (2000 vintage) and I hope to build a new system soon, but I will probably still use this computer for home automation, so I would like to fix my problem...

I installed an Airnet USB 2.0 PCI card (the motherboard only has USB 1).

Everytime I tried to communicate with a USB device connected to it, my system would just freeze. Sometimes it would begin responding again after waiting a few minutes.

I went through some troubleshooting (disabled on-board USB, removed all PCI cards and tried the USB card in different slots, gradually reinstalled all cards...) During this process I eventually learned that reseting the ESCD data before every boot made everything work fine. I further found out that I could restart (ie, no power down) and still be fine, but everytime I booted after a power down, I would need to go in and manually enable ESCD reset.

(when everything is working fine, windows recognizes an enhanced USB controller, but does not when the card isn't working right -there are still USB controllers recognized, just not the enhanced (USB 2.0 I assume).

This is a PITA and I would love to find a solution.

Thanks for any help.

Thanks for the suggestion.

My Bios, under "PnP/PCI Configurations" has these options:

PNP OS Installed Yes/No
Reset Configuration Data Enabled/Disabled

Resources Controlled by Auto(ESCD) / Manual
If manual: IRQ Resources Press Enter
DMA Resource Press Enter
(for Each IRQ and DMA there is the choice of PCI/ISA PNP or Legacy ISA)


PCI/VGA Palette Snoop Enabled/Disabled
Assign IRQ For VGA Enabled/Disabled
Assign IRQ For USB Enabled/Disabled

Regardless of these settings, if I enable Reset Configuration Data, everything works fine (and the setting automatically returns to Disabled).

If I boot from powered down state and don't re-enable Reset Configuration Data, it freezes up on USB activity.

Actually, now that I think about it, my USB 1.1 wireless adapter works fine in any state. The failures occur for my removable drives, bluetooth adapter and printer. Since the printer is USB 1.1, I can't say that only USB 2.0 devices cause the freeze.

I have also checked power requirements for the devices and I don't seem to be overloading anything.

Other BIOS options related to PCI, under Advanced Chipset Features:

CPU to PCI Write Buffer -Enabled
PCI Dynamic Bursting -Enabled
PCI Master 0 WS Write -Enabled
PCI Delay Transaction -Enabled
PCI#2 Access #1 Retry -Enabled
