Compex SRX1224

Some notes on Compex SRX1224 switch.
You plug an null modem cable there, and it does not work? Right?
That's easy. You need the straight, non-null-modem cable! And you need some DB9F-to-DB9F direct converter.
As for switch itself, it is 100Mbs switch, managed from console only, without 802.1Q, just port switch.
UPD: also, for the Nortel/Baystack 325 and 425, you need straight cable, too. But it's a very different device, full of vlans and other useful features.

Some more investigations on Compaq Prosignia VS

I was sure that the board has a memory hole. Nothing like that! It's highly configurable. In the Compaq Setup you can say you have Unix and even Linux installed.
However, BIOS still reports 16M. You have to tell Linux it has more (8 onboard + 4*8 in my case) - so tell Lilo
append="sim710=addr:0x8000,irq:15 mem=exactmap mem=640k@0 mem=15M@1M mem=24M@16M mem=nopentium acpi=off noisapnp"
No matter, still - one of the first thing Linux says - "I've caught NMI!". And linux ignores it. But OpenBSD does not ;-(

Video cards in HP 9000 computers

From time to time I get some HP 9000 video cards and plug them into my hp/ux HPPA computers.
For a long time I could not understand why they are not working: I can see them both in boot and in HP/UX, but hell, they show nothing!
The answer is simple: use at least 1260x1024x75 monitor. Really, I wasted a lot of time trying to understand why I cant run it.
And more, A4552 66501 PCI-X card at least shows something in PCI C160 computer!
