Hi, I booted from the boot disk generated at the end of the Slackware installation procedure and got access back right away. I've restored my original 2.2.16 vmlinuz and System.map, so all I need to do now is generate a working 2.2.18 kernel. Since my last attempt compiled and then gave a kernel panic the following questions spring to mind: 1 - When I'm booting a new kernel, can I redirect the screen output to a file so that I can review the messages generated (including any panics) to aid my trouble-shooting? 2 - Once I've got a good (booting) 2.2.18, how do I update my wonderful boot disk (or create a new one)? Sorry to be a pain, but I promise I'll keep plugging at it until I understand this stuff and then I'll take my turn at helping others who are starting out. I'm saving all of the messages and I'll be using them to create a guide for new blinux-types on my up-coming web site.

Bill's is an ftp site that you can access via anonymous ftp at ftp://speakup.octothorp.org. Once there, cd /pub/redhat and further as appropriate. There is indeed a full Redhat 7.1 installation set. The file you want, and it's path is: /pub/redhat-7.1/d1/images/boot.img This is the image for the floppy. If you don't already have it, you will also need rawrite which is at: /pub/redhat-7.1/d1/dosimages/rawrite.exe This is a DOS executable for creating floppies from floppy image files. NOTE: You may need to kill your screen reader while running rawrite in order to avoid data corruption on the floppy. It may also be advisable to run from an actual DOS boot, or a shutdown to MS-DOS as opposed to running in a DOS window in Windows. You can safely run your screen reader while answering questions from rawrite. It will ask you what file you want to use for the image, what drive to write to, and a third question probably like "press enter when ready." I don't recall the exact sequence, but it's OK to wait until the third question to kill speech. That way, you need only press enter and wait for the floppy to stop spinning. Good luck, and stay in touch about this. We'll get you up in linux yet! <grin> On Tue, 2 Oct 2001, Tim Burgess wrote: > Hi again, > > Do you have the URL for Bill's site and does he have such disks for > Slackware (7.1 in my case)? > > Thanks yet again. > > Tim > > > -----Original Message----- > From: speakup-admin at braille.uwo.ca > [mailto:speakup-admin at braille.uwo.ca]On Behalf Of Janina Sajka > Sent: 02 October 2001 18:18 > To: speakup at braille.uwo.ca > Subject: RE: New Kernel Survival Strategies > > > Hi, Tim: > > Best avenue back to your broken linux system may well be a speakup enabled > floppy that can take you into rescue mode.
