Yes, I was able to build a minimal Jensen config without any warning after pulling today, thanks! I think investing a bit in cleaning up non-PCI configurations may help as soon as PCIe will be obsoleted by the next bus system ;-) > But if it doesn't boot, it's all fairly moot.

The main trouble is that my system has only 64MB of memory and the smallest kernel image with all drivers I need was about 105MB big. According to: http://users.bart.nl/~geerten/FAQ-9.html the Jensen can take up to 128MB of RAM and the required PS/2 SIMMs with partity are still available on ebay, so I just bought 4x32 MB SIMMs. After setting CONFIG_CC_OPTIMIZE_FOR_SIZE the kernel image was still 93MB big, but with 128MB I should be able to boot it.

I didn't had the money for an Alpha at that time, but as soon as cheap systems were available on ebay, I took the opportunity. At the time I bought them, I considered the Miatas (the "Personal Workstations" from DEC) as quite fast - that must have been around 2004/2006. > But at the same time, I really did enjoy it back in the day, and it > _was_ the first port I did, and the first truly integrated kernel > architecture (the original Linux m68k port that preceded it was a > "hack up and replace" job rather than "integrate") My experience is that each port is good for code quality, but I can only state that for user space applications, not having done much kernel work, CU, Uli -- Dipl.
