PC/104 bus looks like any other ISA bus to the system. The only caveats which come to my mind are: * the startup media: if it's going to be a flash disk, make sure it's either IDE flash disk, or DiskOnChip (M-Systems) - otherwise you won't be able to mount/write/read it, * Ethernet controller: FreeBSD 3.0 contains driver for CSxxxx based ethernet cards, which are commonly used in embedded designs. For other chips you must consult LINT very carefully. * you can use PPP, of course, if you have something which looks like a serial port - be it a modem, or a null-modem cable... * my experiments have shown that it's possible to run quite a number of relatively big processes (such as /bin/sh, a number of getty's, SNMP daemon, PPP) on a 386SX with 4MB RAM. YMMV, of course, but the amount of RAM is the critical issue, not the CPU power. One comment here, though: if you _really_ want to use 386 _SX_, you should assume that the kernel is stored uncompressed - decompression takes ca. 90 secs, and it gets boring...
