Hi, > I'll try booting from CDROM with a serial line attached at the weekend, > perhaps that will give us a hint. [You can call the Alpha a dead architecture and the Jensen and antiquated machine, but there are features which modern PCs *still* don't have, like the automatic switch over to the serial line console when no keyboard is connected. I'm still impressed how well that works.] Well...whatever that means, but you can call it a hint. Booting from CD-ROM stopps with: >>> boot dka500 -fl i INIT-S-CPU... AUDIT_BOOT_STARTS ... AUDIT_CHECKSUM_GOOD AUDIT_LOAD_BEGINS AUDIT_LOAD_DONE Linux/AXP bootloader for Linux 5.15.0-rc2-00045-gcf1d2c3e7e2f-dirty Switching to OSF PAL-code ..
