Pratt) Subject: copy-image-to-partition dd.exe wanted Date: Wed, 1 Dec 1993 05:31:24 GMT I have a laptop (Gateway Handbook 486DX2-40) whose external floppy drive is still on order. While I'm waiting, I'd like to try installing Linux on it. Although I've been able to create a Linux partition and install a boot redirector MBR that can reach either partition, I haven't been able to put the Linux bootdisk, which normally boots from the floppy, in a place where the boot redirector can reach it. I'd like to copy bootdisk to the beginning of the Linux partition. Does anyone have a .exe that copies a file to a partition? I.e. the functionality of Unix's dd if=myfile of=/dev/hda2 There is a Linux-related DOS utility, rawrite.exe, which comes close, but can only write to floppies, I need to write to the hard drive. I'm not sure which is the bigger puzzle, how to do this or why why neither DOS nor Norton utilities offers such a basic and easily implemented capability. -- Vaughan Pratt pratt@cs.stanford.edu boole.stanford.edu:/pub/ABSTRACTS ------------------------------ From: davem@extro.ucc.su.OZ.AU (David Monro) Subject: Re: Appletalk under LINUX?

(Don't get this card, though - it is slow and jams on occasion. Like often.) Other cards which are supported in promicuous mode appear to be: Allied Telesis AT1700 (at1700.c) Intel EtherExpress (eexpress.c) (not yet I think) AMD LANCE (lance.c) Whether the other cards don't have it, or the drivers just don't use it I don't know. Can't see why a card wouldn't have it, sounds like a useful feature to me. Note I think these features are new to the 0.99.14 kernel, and I have no idea at all how one accesses the incoming promiscuous packets. David Monro >Greetings from Heidelberg >: -- >: Michael A.

The code in the linux* kernel assumes that if the printer is off line then it will be active, but my printer seems to leave it alone, unless it is out of paper. This is my gut feeling as well. This means I don't get any messages when the printer is off line. Any body got some hard documentation? (My printer is an OKI Microline 380 - the manual says about the fault line: 'When the paper end is detected, this signal changes from high to low level.' This seems to be exactly what happens.) ( For kernel hackers: the culprit is line 143 of lp.c - to make it work for me I just add a check for LP_PSELECD as well.)

Answer "yes" to the question, whether you want IPC support, when configuring your kernel. As far as I know, both DOSEMU and POSTGRES use it. (Well, I know it for sure for the latter).
