qemu:access existing partitions

I managed also to start in addition with '-hda /dev/hda1' without complaints from qemu after making /dev/hda1 world readable. Experiments with mountpoints failed. But Partitions.Show doesn't recognize any partitions with a type. So did anybody have more success concerning booting qemu with existing disks on Linux and mounting a FAT32 or AosFS partition ? Perhaps it should be possible to dump an AosFS partition to a file ? Or formating a file with AosFS ?

I've got a problem with this, since 'int string' is a subset of 'string'. I thought such BNF needed the alternatives to be mutually exclusive ? I guess the scanner is used to read a 'token', which should be either: <an integer string>, "USER", "PASSWORD", "CALL" <string>. Where <string> (using the notation of 'System.Text') is a char-string other than the other 4 posibilities listed above. > > According to the semantic > specification, the command should have the effect of a > "continue" statement.

If we can consolidate effort in the future, your documentation will be appreciated. BTW, since you're looking at this, how would I do the following: an aquaintance in the neighbouring town, has a WinXX machine + modem, but little familiarity. We want to be able to: I'll dial him, via n-o of course, and download his text and upload my text. I've got an old DOS based BBS application, which could do it, but unfortunately he can/will only use Winxx - cartoon based. == Chris Glur.

BlueBottle with Samsung SC140B CD
by Aubrey McIntosh 08 Sep '04

08 Sep '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 My Dell OptiPlex GX1 was outfitted with a Samsung CD-Master 40E SC-140B CD drive manufactured June 1999. This drive works under Windows 2000 to my satisfaction. After some time, I have determined that Bluebottle will not work with this CD on two different test machines. The replacement, a BTC 24X CD-ROM SLL24, works fine, and I can now boot Bluebottle on the Dell (yeah!) I have not investigated the firmware upgrade status for the Samsung. I will send this CD to whoever wants it, as follows: 1. You pay shipping. I can get an exact quote before you commit, if necessary. 2. You express interest in developing an Oberon family driver. 3. If you abandon the driver project, you make it available on these same conditions. 4. It goes on eBay if the Oberon community is unresponsive. -----BEGIN PGP SIGNATURE----- Version: PGPfreeware 7.0.3 for non-commercial use <http://www.pgp.com> iQA/AwUBQT7tRQKlSw8yssF7EQIM2wCfSY8/UjbTnqCglF6N/wgfj24clyIAoMjf H8yEiTOXXLDEaRKCaUIa/AkI =ezc4 -----END PGP SIGNATURE-----

Jack Johnson <knapjack(a)gmail.com> wrote: > qemu -hda somefile -cdrom AosCD.iso -boot d Could you elaborate what that means ? Could it be possible to run an Oberon from a CD using a 86 emulator on a 86 Linux machine ? Can Oberon access the harddisk or a AOS partition on this harddisk ? Sounds funny. During my holidays I was addicted to an online game (www.ogame.de Sorry, is German) which I can play by browser. So I would be interested in a means to work with Bluebottle and at the same time having the chance to have a look once in while whether I can start building another crystal mine, build some battleships or defend against a raiding space fleet :-) Cheers, Edgar -- edgar(a)edgarschwarz.de, Running Bluebottle www.edgarschwarz.de Make it as simple as possible, but not simpler !

Thanks, knapjack, for tipping me to QEMU. Let us arrange to have a Bluebottle image at the FreeOSZoo homepage http://www.freeoszoo.org/download.php . I'll try to install QEMU today. Word, sr

Bluebottle + QEMU = Wahoo!
by Jack Johnson 06 Sep '04

06 Sep '04

Just tried Bluebottle under the QEMU x86 emulator. No networking, though (NE2k drivers needed, plus some host-side config I need to tackle), but it works like a charm. You will see what looks like corrupt video at boot, but give it a few seconds and it clears up. It looks like initializing the video takes longer than anything. -Jack

simplifying Dialer.DoScript
by shark＠gulfnet.sd64.bc.ca 03 Sep '04

Oberoners, Here is a question about Dialer.DoScript. System.Text in PC Native 05.01.2003 describes the receive command of the Dialer script thus. " rcv = int string . wait up to int seconds for string to be received, abort on failure" If the string is empty, there is nothing to wait for and nothing is received immediately. According to the semantic specification, the command should have the effect of a "continue" statement. In reality the specified time elapses and the script aborts. Mgetty in Linux provides a ringback dialing protocol (google "mgetty ringback") which allows a telephone line to be used for both voice and modem communications. The initiating modem dials, waits for a ring or two, hangs up, waits a few seconds and then dials again. mgetty answers the second call. Most modems do not provide a command for pausing between two dialings. The existing Dialer does not provide a pause. The "simple-minded" solution here is to implement a PAUSE macro. For example "PAUSE 6" to invoke a 6 second pause. Alternatively, an empty wait string could invoke a pause. Semantically this would be a special case. If someone can suggest another approach, I am interested. Also, there might be a good argument against pausing for the empty wait string. Thanks, Peter E. http://carnot.pathology.ubc.ca/
