You will need to use a serial console. - - Multia has only one 32 bit PCI slot for expansion, and it - is only suitable for a small form factor PCI card. By - sacrificing the PCI slot space you can mount a 3.5" hard disk - drive. Mounting stuff may have come with your Multia. Adding a - 3.5" disk is not a recommended upgrade - due to the limited power rating of the power supply - and the extremely marginal cooling of - the system box. - - Multia also has 2 PCMCIA expansion slots. These are - currently not supported by &os;. - - The CPU might or might not be socketed, check this before - considering CPU upgrade hacks. The low-end Multias have a - soldered-in CPU. - - Multia has 2 serial ports but routes both of them to the - outside world on a single 25 pin sub-D connector. The Multia FAQ - explains how to build your own Y-cable to allow both ports to be - used. - - Although the Multia SRM supports booting from floppy this - can be problematic. Typically the errors look like: - - *** Soft Error - Error #10 - FDC: Data overrun or underrun - - This is not a &os; problem, it is a SRM problem. The best available - workaround to install &os; is to boot from a SCSI CDROM. - - There have been reports that you sometimes need to press - Control-Alt-Del - to capture the SRM's attention. I have - never seen this myself, but it is worth trying when you are greeted - by a blank screen after powerup. - - Sound works fine using &man.pcm.4; driver and a line in the - kernel configuration file as follows for the Crystal CS4231 - chip: - - device pcm - - The sound device lives at port 0x530, and uses irq 9 along - with drq 3. You also need to specify flags 0x15 in the device.hints file. - - I have not yet been successful in getting my Multia with - the AD1848 to play any sound. - - While verifying playback I was reminded of the lack of CPU - power of the 166MHz CPU. MP3 only plays acceptable using 22kHz - down-sampling. - - Multias are somewhat notorious for dying of heat - strokes. The very compact box does not really allow access to cooling air. - Please use the Multia on its vertical stand, - don't put it horizontally (pizza style). Replacing the - fan with something which pushes around more air is really - recommended. You can also cut one of the wires to the fan speed - sensor. Once cut, the fan runs at a (loud) full speed. - Beware of PCI cards with high power consumption. - If your system has died you might want to check the - Multia-Heat-Death pages at the - NetBSD Web site - for help in reviving it. - - The Intel 82378ZB PCI to ISA bridge enables the use of an - IDE disk. This requires a line in the kernel configuration file - as follows: - - device ata - - The ATA interface uses IRQ 14. - - The IDE connector pin spacing is thought for 2.5" laptop - disks. A 3.5" IDE disk would not fit in the case anyway. At - least not without sacrificing your only PCI slot. The SRM - console unfortunately does not know how to boot from IDE - disks. You will need to use a SCSI disk as the boot disk. - - In case you want to change the internal hard drive: the - internal flat cable running from the PCI riser board to the - 2.5" - hard drive has a finer pitch than the standard SCSI flat - cables. Otherwise it would not fit on the 2.5" drives. There are - also riser cards that have a standard-pitch SCSI cable attached - to it, which will fit an ordinary SCSI disk. - - Again, I recommend against trying to cram a replacement - hard disk inside. Use the external SCSI connector and put your - disk in an external enclosure. Multias run hot enough as-is. In - most cases you will have the external high density 50-pin SCSI - connector but some Multia models came without disk and may lack - the connector. Something to check before buying one. - - The kernel configuration file for a Multia kernel must - contain: - - options DEC_AXPPCI_33 -cpu EV4 - - Recommended reading on Multia can be found at - - http://www.netbsd.org/Ports/alpha/multiafaq.html - or - http://www.brouhaha.com/~eric/computers/udb.html. - - - Personal Workstation (<quote>Miata</quote>) @@ -2373,112 +2178,6 @@ cpu EV5 cpu EV5 - - AlphaServer 8200 and 8400 (<quote>TurboLaser</quote>) - - The AlphaServer 8200 and 8400 machines are enterprise servers. - Expect a tall 19" cabinet (8200) or fat (8400) 19" rack. - This is big iron, not a hobbyist system. TurboLasers are multi-CPU - machines, up to 12 CPUs can be in a single machine. The TurboLaser - System Bus (TLSB) allows 9 nodes on the AS8400 and 5 nodes on - the AS8200.

Maximum memory is 28 GBytes. - - - expansion: 3 system I/O ports that allow up to - 12 I/O channels each I/O channel can connect to - XMI, Futurebus+ or PCI boxes - - - - &os; supports (and has been tested with) up to 2 GBytes - of memory on TurboLaser. There is a trade-off to be made between - TLSB slots occupied by memory modules and TLSB slots occupied by - CPU modules. For example you can have 28GBytes of memory but only - 2 CPUs (1 module) at the same time. - - Only PCI expansion is supported on &os;. XMI or - Futurebus+ (which are AS8400 only) are both unsupported. - - The I/O port modules are designated KFTIA or KFTHA. The - I/O port modules supply so called hoses that connect to - up to 4 (KFTHA) PCI buses or 1 PCI bus (KFTIA). KFTIA has - embedded dual 10baseT Ethernet, single FDDI, 3 SCSI Fast - Wide Differential SCSI buses and a single Fast Wide Single Ended - SCSI bus. The FWSE SCSI is intended for the CDROM. - - KFTHA can drive via each of its 4 hoses a DWLPA or DWLPB - box. The DWLPx house a 12 slots 32 bit PCI backplane. Physically - the 12 slots are 3 4-slot buses but to the software it appears - as a single 12 slots PCI bus. A fully expanded AS8x00 can have - 3 (I/O ports) times 4 (hoses) times 12 (PCI slots/DWLPx) = - 144 PCI slots. The maximum bandwidth per KFTHA is 500 - Mbytes/second. DWLPA can also house 8 EISA cards, 2 slots - are PCI-only, 2 slots are EISA only. Of the 12 slots 2 - are always occupied by an I/O and connector module. DWLPB are the - prefered I/O boxes. - - For best performance distribute high bandwidth - (FibreChannel, Gigabit Ethernet) over multiple hoses and/or - multiple KFTHA/KFTIA. - - Currently PCI expansion cards containing PCI bridges are - not usable with &os;. Don't use them at this time. - - The single ended narrow SCSI bus on the KFTIA will turn up as - the fourth SCSI bus. The 3 fast-wide - differential SCSI buses of the KFTIA precede it. - - AS8x00 are generally run with serial consoles. Some - newer machines might have a graphical console of some sorts - but &os; has only been tested on a serial console. - - For serial console usage either change - /etc/ttys to have: - - console "/usr/libexec/getty std.9600" unknown on secure - - as the console entry, or add - - zs0 "/usr/libexec/getty std.9600" unknown on secure - - For the AlphaServer 8x00 machines the kernel config file - must contain: - options DEC_KN8AE # Alpha 8200/8400 (Turbolaser) -cpu EV5 - - Contrary to expectation there is no cpu - EV6 defined for inclusion in the kernel config - file.
