New release available: SqueakNOS-08-Aug-2006.iso

This release was reorganized for a clearer distribution and to be in synch with the article "SqueakNOS: Building, changing, booting and installing.".

It also has Lance and Realtek8139 network cards initialization by default, as well as TCP/IP stack initialization, except for setting up the IP address, which should be done from the Workspace.

New article posted

I posted a new article in the SqueakNOS series: SqueakNOS: Building, changing, booting and installing. Take a look if you are interested in making modifications to SqueakNOS (and testing the modifications). Or if you want to make a bootable USB disk with SqueakNOS.

RTL8139 working and NetSqueak integrated into SqueakNOS

Realtek8139PCIDevice can receive and send perfectly!!! but way more important, Luciano is working a lot on NetSqueak and now we have integrated all his work in SqueakNOS, and... IP, ARP, ICMP are working, UDP should be working and TCP is almost working (You can open a listening port in SqueakNOS and telnet from outside for example, or you can open an outgoing connection). New release coming soon

Almost booted on Macbook pro.

We used BootCamp with a modified version of GRUB including the A20 patch. (We will release this new GRUB with next SqueakNOS release, if you need it, mail us).

The video mode was correct, but then, when SqueakNOS started toying with hardware I/O ports the Macbook pro froze... we were not surprised to see it freezing, as all hardware must be different, but it was nice to see that it's at least booting, and that the problem now must be solved in Squeak and not natively. We are not going to put much more time on this right now though.

Realtek8139Device transmit working

I have just commited to Monticello Realtek8139PCIDevice. This is a device supporting Realtek RTL8139 10/100 Ethernet card. Right now it only supports receiving, but in a much better way than the LancePCIDevice (this RTL device uses a 64kb circular buffer as supported by the card, the LancePCIDevice still does not support the circular linked list feature).
Transmiting is not supported yet, but should not take long to do... stay tunned!

New release: Networking is working! :-)

Only support for a single Network Card (the one emulated by vmware). You can boot the image we just released, and ping!

get it: http://sourceforge.net/project/showfiles.php?group_id=3891&package_id=3865

New screenshot

I just added a new Screenshot of SqueakNOS receiving packets using IRQs, and showing them in the Transcript.
For this we're using NetSqueak (http://www.squeaksource.com/Net.html)

https://sourceforge.net/project/screenshots.php?group_id=3891&ssid=37701

You can see the first packets are ARP requests, then and ICMP EchoRequest (ping) and then an incoming TCP SYN request to port 23. Packet sending is not implemented yet, so I had to manually set the mac address using 'arp -s' on the source box.

hah! More happines! I just filed in Luciano's Packets from http://community.corest.com/~luciano/conduits/ into my SqueakNOS, and could finally see the EthernetPackets as they should be. Now, handling the IRQs for the LancePCIDevice (netowrk card) I see in the Transcript all packets decoded properly :-)

All this time I was quiet I wasn't really quiet, I was working on implementing the LancePCIDevice, a device for supporting Lance network cards. However, it's taking quite some time... The pdf describing how the card works has roughly 300 pages, and most of them describe each of the 16 bits of 150 hardware registers of so. We don't need them all of course, but have now 140 methods in 4 classes... And I finally got something I could try, but it didn't work :-(

But I'm not giving up on it ever!
