You can MOUNT a DOS partition, and deal with it as a completely accessible filesystem, (with dos filename restrictions of course). I had trouble once with mtools, and don't recommend it for regular accesss to a hard disk. But you might as well mount your DOS partition, since it gives better, faster access. -- David L.

In fact, most of the new manufactured IDE hard drives are all claiming to be the Enh/Fast/Mode3 hard drives. Without a ENHANCED/MODE3 VL-BUS controller, those drives work just like the ordinary/mode2 hard drives. I tried a Seagate(Enh) HD with Acculogic Enh(mode3) IDE controller 3 months ago and encountered some problems. I think the controller is to blame. But without certain controllers and drivers, those drives will not take advantage of mode 3 features. I assume that Linux will need a patch to enable the Enh IDE function. Now I have a Seagate mode2, a Maxtor mode3 and an ordinary VLB IO/IDE controller without a problem. And the Maxtor's (master drive) performance doesn't seem to boost.

BUT, I'm not going to do this unless I can get a foolproof way of moving files back and forth from one machine to another. What I envision is some DOS or linux command that will copy a file from my linux partition to my DOS partition. I realize that I could use FTP, but I would need a third computer to use for temporary storage if I did this. What I'm looking for is something completely and totally self-contained. I realize that this has, in all likelyhood, allready been done.

Boot from the install floppy, log in as : install, and follow the on-screen directions. Well, just my two cents worth RE: FA94 release. I had Yggdrasil ship me out a fall release red he day they got it in. It seems that when you try to install additional software via the graphical control panel, they forget to unlink the /usr link from /system_cd/usr, so all cp commands to /usr get a read-only file system error. My solution was to manually copy the whole /system_cd/usr to /usr (which is linked to my /scsi/linked/usr directory) with cp -Rd, and then remove and link the source tree. You should be able to do a "rm /usr" after the control panel is running and have it work. Unlike the SP94 release, they do not install anything into /usr. RTFM doesn't work all the time.

Here's the most important thing to remember: *When using a multi-homed host as a router, EACH interface must have it's own address.* Routing on your local host tells IP where to send packets, based on their destination address. What you _tell_ the routing code is _which interface_ to send the packets out on. Therefore, each interface, (PPP is an interface) must have a unique address. Usually, you get the IP address for your PPP interface from the provider's net, either statically, or dynamically. The "inside" address, the one you ifconfig onto your ethernet interface, is part of your private net (either one you've registered yourself, or part of a block assigned by your provider.) A typical route information output in such a case might look like this... Destination Gateway Netmask Flags MSS iface 127.0.0.1 127.0.0.1 255.0.0.0 UH 1536 lo0 199.245.227.0 199.245.227.254 255.255.255.0 U 1436 eth0 default 198.147.221.1 255.255.255.0 U 1436 ppp0 (The person I'm helping with this right now, who owns those addresses, will recognize them... :-) This routes packets for the local host to the loopback interface, packets for the local net (199.245.227) to the local interface which connects to that net, and packets for every other network number to the PPP interface, for forwarding to the outside world.
