But in netboot/ns8390.c, a few statements do so. We can get the datasheet from <http://www.national.com/pf/DP/DP83902A.html>; (This datasheet is DP83902A, but according to "Features", it is 100% software compatible with DP8390) >How-To-Repeat: None >Fix: --- /usr/src/sys/i386/boot/netboot/ns8390.c.orig Thu Jun 12 13:33:50 1997 +++ /usr/src/sys/i386/boot/netboot/ns8390.c Thu Jun 12 13:36:07 1997 @@ -480,9 +480,19 @@ if (!(rstat & D8390_RSTAT_PRX)) return(0); bound = inb(eth_nic_base+D8390_P0_BOUND)+1; if (bound == eth_memsize) bound = eth_tx_start + D8390_TXBUF_SIZE; - outb(eth_nic_base+D8390_P0_COMMAND, D8390_COMMAND_PS1); + if (eth_flags & FLAG_790) + outb(eth_nic_base+D8390_P0_COMMAND, D8390_COMMAND_PS1 | + D8390_COMMAND_STA); + else + outb(eth_nic_base+D8390_P0_COMMAND, D8390_COMMAND_PS1 | + D8390_COMMAND_RD2 | D8390_COMMAND_STA); curr = inb(eth_nic_base+D8390_P1_CURR); - outb(eth_nic_base+D8390_P0_COMMAND, D8390_COMMAND_PS0); + if (eth_flags & FLAG_790) + outb(eth_nic_base+D8390_P0_COMMAND, D8390_COMMAND_PS0 | + D8390_COMMAND_STA); + else + outb(eth_nic_base+D8390_P0_COMMAND, D8390_COMMAND_PS0 | + D8390_COMMAND_RD2 | D8390_COMMAND_STA); if (curr == eth_memsize) curr=eth_tx_start + D8390_TXBUF_SIZE; if (curr == bound) return(0); if (eth_vendor == VENDOR_WD) { >Audit-Trail: >Unformatted:
