Hi, I've been away from udpcast for awhile. Now I am using it for imaging on a cluster. I'm having difficulty booting from CDROM with working serial console. I can boot the system with PXE and run the Debian installer over serial console OK, and Debian booted from hard drive will display and control OK over serial. With ISOLINUX, it shows a little progress over the serial console, and then it is silent. I started with the udpcd.iso (as of May 24, 2012 on the udpcast website), mounted it, copied to an 'extracted' directory and added my options for serial console. Here is my ISOLIUX.CFG : serial 0 default linux label linux kernel linux append root=/dev/ram0 initrd=initrd console=ttyS0,9600 I run genisoimage within the "extracted" directory copy: genisoimage -o ../serial-udpcd.iso -b ISOLINUX.BIN -c boot.catalog -no-emul-boot -boot-load-size 4 -boot-info-table . It will get as far this: ISOLINUX 3.63 Debian-2008-07-15 Copyright (C) 1994-2008 H. Peter Anvin boot: Loading linux................ Loading initrd.................................................................. ...................................................ready. I've tried current syslinux files for isolinux.bin and pxelinux.0 Same result: ISOLINUX 4.05 2011-12-09 ETCD Copyright (C) 1994-2011 H. Peter Anvin et al Loading linux... Loading initrd..........ready. I've tried CONSOLE 0 within ISOLINUX.CFG and it causes the ISOLINUX banner to appear and that is all. Here is the pxelinux.cfg/default which works OK with the Debian installer... SERIAL 0 9600 CONSOLE 0 SAY debug include debian-installer/amd64/boot-screens/menu.cfg default debian-installer/amd64/boot-screens/vesamenu.c32 prompt 1 timeout 300 Then within one of the boot-screen menu files txt.cfg: default install label install menu label ^Install menu default kernel debian-installer/amd64/linux append vga=788 initrd=debian-installer/amd64/initrd.gz -- quiet noapic acpi=off console=ttyS0,9600 earlyprint=serial,ttyS0,9600 The kernel from udpcast doesn't like all of these options, so they were tried and removed. The systems are Sun V20z and they are connected with a serial hub. I thought maybe I could save on some CDs by asking for some help. :-) My thinking is to use CDROM for uploading master disk image, and PXE for automated imaging. It should prevent mistakes. --Donald Teed _______________________________________________ Udpcast mailing list Udpcast(a)udpcast.linux.lu https://udpcast.linux.lu/cgi-bin/mailman/listinfo/udpcast
