Have you seen these drivers -> http://www.smlink.com/main/index1.php?ln=en&main_id=32 It seems to support a lot of software modems, ie HAMR5600 based AMR/CNR/MDC/ACR modem cards on the following Southbridge chips: - Intel ICH0, ICH2 - Via 686A, 686B, 8231, 8233 - SiS 630 - ALI 1535. SmartPCI56, SmartPCI561, SmartPCI563 based PCI modem cards. SmartUSB56 based USB modem. And the binary code appears to only call shim routines for which the source is available. -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 9A8C 569F 685A D928 5140 AE4B 319B 41F4 5D17 FDD5
