Hello 9fans, I have been talking with Benavento and Lucio to get a 486 terminal working. I decided to share it with you to get some ideas of where to start debugging.
> I created a boot floppy, to configure a plan9 terminal using > sirviente.9grid.es as cpu, and got a tons of lines with: > > "mapfree unallocated unmapped physical memory" I have discarded hardware problems because I tested the machine with a QNX floppy and the network card worked. I could browse through some www pages. The previous errors were produced because the kernel was trying to allocate more memory than the system had. I added *maxmem=67108864 to PLAN9.INI (the system has 64Mb of RAM) and these errors dissapeared. Following Lucio suggestion I also added *noe820scan=1. I reach the prompt: #l0: NE2000: 10Mbps port 0x300 irq 9 addr 0x4000 size 0x4000: 004f4c0141b5 64M memory: 27M kernel data, 36M user, 163M swap root is from (tcp) [tcp -g 192.168.1.1 ether /net/ether0 192.168.1.5 255.255.255.0]: user[none]: vejeta boot: can't connect to file server: connection time out panic: boot process died: unknown panic: boot process died: unknown dumpstack disabled cpu0 exiting - - - - - - - - - - - - - - - - - - - - I tested the same floppy in another machine, a Pentium II with same network card, and it could boot successfully and reach 9grid.net as cpu server. So I have discarded router misconfigurations too. Launching a sniffer and monitoring the network in another machine showed that there weren't any output coming from 192.168.1.5. My current PLAN9.INI is as follows: - - - - - - - - - - - - - - - - - - - - - - - - - - - ether0=type=ne2000 port=0x300 irq=9 mem=0x4000 # nodummyrr bootfile=fd0!dos!9pc.gz fs=91.121.95.142 auth=91.121.95.142 authdom=91.121.95.142 bootargs=tcp -g 192.168.1.1 ether /net/ether0 192.168.1.5 255.255.255.0 #bootdisk=local!#S/sdC0/fossil *nomp=1 *nodumpstack=1 *noe820scan=1 *maxmem=67108864 *kernelpercent=40 #partition=new #dmamode=ask *nobiosload=1 *noahciload=1 *debugload=1 mouseport=0 #0 para el COM1 y 1 para el COM2 monitor=xga vgasize=800x600x8 -- Fidonet: 2:345/432.2
