| * Daniel J. Rodriksson: Modified sbintr to handle 8 and 16 bit interrupts |
| * for full duplex support ( only sb16 by now ) |
| * Rolf Fokkens: Added (BETA?) support for ES1887 chips. |
| * (fokkensr@vertis.nl) Which means: You can adjust the recording levels. |
| * |
| * 2000/01/18 - separated sb_card and sb_common - |
| * Jeff Garzik <jgarzik@pobox.com> |
| * |
| * 2000/09/18 - got rid of attach_uart401 |
| * Arnaldo Carvalho de Melo <acme@conectiva.com.br> |
| * |
| * 2001/01/26 - replaced CLI/STI with spinlocks |
