AGP video card.
by Sean Cody 04 Jun '11

04 Jun '11

I am in need of a decent AGP Video card with DVO for my brother to connect his T-Bird Shuttle PC to his LCD TV. I had purged my collection of legacy gear earlier this year and the cards I have left are fried. I don't need new, just AGP and DVI with basic GPU acceleration (he just watches video at 720p,via DVI->HDMI adapter). If it works/supported with Linspire all the better. -- Sean (mobile)

burning large files
by Trevor Cordes 04 Jun '11

04 Jun '11

I need to burn a 5GB+ data file to DVD-DL, using command line tools in linux. Obviously burning small (sub 2 or 4GB) files to DVD is easy using mkiso and cdrecord, or whatever. Now I need to burn a large file and I'm discovering it's not so easy. It turns out there's a file size limit for ISO9660 of 4GB. Doing a bit of research, it looks like you must burn UDF format instead of ISO, but the UDF burning utilities on linux are limited. mkisofs has options -udf and -allow-limited-size which may solve my problem, though the "alpha" labelling of it doesn't inspire confidence. My other issue is I need to know exactly how much usable (non-FS) data space I get out of a DVD-DL. That number is well known down to the byte level for ISO9660 on DVD (single layer). I'm having a really hard time finding hard numbers for DVD-DL and UDF overhead. One would assume you get DVD-SL x 2 raw space. And one could probably guess at some reasonable overhead for UDF. Still, hard numbers will help me avoid coastering a multi-$$ DVD-DL blank. Hopefully someone has some experience with this? Thanks!

Usually it's the other way 'round, as the mgmt port is used for remote "lights-out" installs. You can connect to a virtual console port through the sun mgmt port, so you should never need both.

What its usually meant by that is that you must physically put the RSC module into the server, and you must cover give it an IP address, etc. before you can do anything with it.

Not if there's a frame buffer installed. And that sound like you're in the host serial port, not the management port. Which do you want to be connected to?

Turn off hardware flow control (RTS/CTS or DTS/DSR) and use software flow control (XON/XOFF) instead. Also, if you don't want to use minicom, (the modem AT initialization is a pain to turn off completely) just use screen instead: "screen /dev ttys0 9600" -Adam Kevin McGregor <kevin.a.mcgregor(a)gmail.com> wrote: >This is driving me nuts, since it was working and now it isn't and I have no >idea what has changed.

Unless Sun radically changed their approach since I last worked with current great, the LOM port won't support flow control at all. By definition, software flow control is handled by whatever is processing your input, so either the LOM f/w or the Solaris tty layer. The serial port on the host itself (i.e. /dev/cua0) does support h/w flow control, and would normally be set to 115.2kbps if you're doing a lot of work there anyway. That's one of the rationales to leaving console ports at 9600, no flow control: everything can handle that without buffer overflows, you only need a 3-wire serial cable, and it's transparent to ^Q/^S in case that's important (or in case the connected device handles it, as in UNIX, printers, Cisco IOS, etc.). -Adam JohnD <jd(a)westman.wave.ca> wrote: > >Thirded on screen. > >But if you do a lot of binary xfer, the hw flow control may be worth a bit more patience. >And you can then use Ctrl_S (xoff**) and Ctrl_Q a bit more freely (e.g: scrollstop -vs- /usr/bin/less; since you're only extruding at 9600), and yer scroll >states won't get obfuskomacated. > >Check BIOS/CMOS settings on both machines, for mbrd's integrated UART/ComN (toggles). >Old IBM defaults for primary&secondary were irq4:3F8 and irq3:3E8 > >Check PSU for negative12v on psuPin12 (usu.blue) -vs- adjacent psuPin13 (black:grnd) > >In rs232 terms, the DSR+[D]CD (usu.combined) & CTS signals minicom wants to see asserted from the OtherEnd, ain't. > >Since MrCyan's prolly a NullMdm/CrossoverCable, ThisEnd's handshakes*** are actually coming from OtherEnd's DTR or RTS pins, resp. >You may think MrCyan is weird, but that MrMagenta is a downright reservoir dog. > >Curious my ageing brain still responds to AT&F, but I can't juggle this newfangled capex or optex without fumbling the PON > >John Donovan >planet Brandon > >** pardon my language > >*** speaking of language, would the modern vernacular now be 'Data Daps' ? > >In which case, then let us lower our respective altitudes and engage in pheremonally fragrant activities on the dancefloor >(transl: 'Get down, get funky.') > >_ _ _ _ _ _ _ _ _ _ _ > >On ImpossibleDate(01/-10/-28163) 01:59 PM, Kevin McGregor wrote: >> This is driving me nuts, since it was working and now it isn't and I have no idea what has changed.
