Time Event
Big RAM block device
I need to make a 1G block device in memory. (the machine has 4 GB of memory)

Never having done this before, I found rd.o from the block devices section of the kernel config. Did a bit of reading. Was able to make 1 MB, 10 MB, and 100 MB devices (modprobe rd rd_size=1kblocks), and then dd /dev/zero onto them, and then make a filesystem and mount it. No problem.

BUT... when I try to make a 1 GB ram disk, I kill the machine, or some of it:

RAMDISK driver initialized: 16 RAM disks of 1000000K size 1024 blocksize
garrison:~# dd if=/dev/zero of=/dev/ram1 count=2000000
Connection to garrison closed by remote host.
Connection to garrison closed.

lj@mayor:~$ ping garrison
PING garrison.lj ( 56 data bytes
64 bytes from icmp_seq=0 ttl=255 time=0.2 ms
64 bytes from icmp_seq=1 ttl=255 time=0.1 ms

lj@mayor:~$ ssh root@garrison
ssh: connect to address port 22: Connection refused

I imagine I just killed the VM, trying to allocate all that memory so fast from the buffer cache, which is already mostly in use. I looked through rd.c, but couldn't see anything to suggest a max size.

hey... this is my first post.
i got dragon linux.
i am also trying to install corel linux, the problem is wen it starts the setup the screen gets all knarled.i have a tirdent blade 3d agp grafix card. umm so i cant see it. any ideas on how to fix it?
also i am considering downloading red hat? should i bother downloading it?
or wat should i get?
installing dragon again..... i wonder if i get it to work this time...... so much more stable than windows.
ok lets see. ive finnished installing dragon, i then set up my video with xf86config but it still dont work the screen flicks and goes black wen i use startx.. umm any help on how to get it to work would be nice.
Linux Video Cards
I'm looking to get a new video card for my linux box. The one I have no is really old and it won't run X worth a damn. I need a video card that will run X at a decent resolution, and has good driver support. Doesn't need to do anything special. Any cheap recommendations?
Does anyone have an X-windows usenet program they like? Knode isn't that great, it would be really nice if the ximian people put out a newsreader..
