IBM T41 + Sandisk Cruzer 512mb + DSL 0.9.2Forum: USB booting Topic: IBM T41 + Sandisk Cruzer 512mb + DSL 0.9.2 started by: phoneboy Posted by phoneboy on Jan. 30 2005,11:32
Trying to USB Boot with this combination. Get fairly far as syslinux comes up, can type in a boot option, and it goes through the boot process. When it tries to mount the knoppix ISO from the USB Flash, it tries to locate a DSL image in just about every SCSI device it thinks might exist. It gives up after several minutes and rolls over to /dev/sda1. However, it fails to mount the /KNOPPIX directory as all the files it is looking for aren't there and the kernel panics. Any idea? Also please note that I have other Linux boxes here, so if I need to further modify the USB card, let me know Linux equivelants if they exist. Posted by Max on Jan. 30 2005,17:09
I have a T42 and a 512MB DataTraveler. I had tried all kinds of methods (following this and that forum message) but could not get it to boot off USB. Then I finally just tried the automated menu script (Install to USB) and it worked. I couldn't believe it after all I had went through.The first partition on the stick was 200MB and of type FAT. The second is the the rest of the stick. It seems that the T42 sees the USB stick as a "hard drive" so the system doesn't care if the first partition is < 128MB and the cylinders and sectors are perfect. One problem I did have was that sometimes during the boot loading the system would quit responding to the USB port. Most of the time is was about 1/3 of the way through booting, but other times it was after so I'd go to load a DSL extension and it would just hang. I think this is something related to the IBM motherboard and not the USB stick. Hopefully it was just an anomoly on this system. Since then my 4 yr old son watered the plants with the hose from the sink and denched my T42 that was on the couch and fried the motherboard. Our IT break/fix guy happily replaced to MOBO under warranty when he couldn't diagnose the problem??? (He just couldn't figure out how so much condensation had formed in the case....) I think I'll try booting off USB again now to see if that hardware problem went away.... Good luck. Posted by phoneboy on Jan. 30 2005,22:06
Well I solved my own problem. Turned out one of the USB Modules that was loaded was not allowing me to remount /dev/sda1. I thought something was strange when booting off cdrom and booting off of the USB stick gave me a difference in USB modules that were loaded. On the USB stick, it loaded an ehci module, which it did not load when booting from CD. Removed that entry from the USB_MODULES line in linuxrc and it started booting! W00t!
