Here's how the formatting of the SD card is done.= First you partition the disk into n 'FAT 12" partitions, one for = each drive you wish to connect. Then you pop the card in the emulator board= , and run a utility which formats the partitions as "Linux" and y= ou then have n 10.5MB Linux partitions. Putting the card back into your hos= t machine, you then copy your RL02 disk images to the newly formatted Linux= partitions.

Here's the full explanation:

Not a problem: if you hook up the -11's console to another computer, yo= u
can download a bootstrap into it over the serial line, using the -11's = ODT.

Thanks for the tip.

Speaking of booting, I ha= ve Mini-Uix booting under an -11/05 simulator
(Ersatz-11); I used the RK image from here:

Thanks again.
=C2=A0
Oh, I recently realized how to make a=C2= =A0 bit more room on an -11/03: most
DEC small QBUS memory cards allow you to use half the 'I/O page' fo= r memory,

Sounds beyond me, and not necessary at thi= s stage.
=C2=A0
What kind of memory card(s) do you have for the -11/03?


The 256kB card is:
M8067-KAMSV11-PK256-kbyte MOS memory with parity CSR
=C2=A0I'll keep that for the '23+.

Can you clarify something for me regarding memory? I= understand=C2=A0the bottom area of memory in a Unix system is for the Kern= el and it's stuff, and that the top 8kB is set aside for device I/O (wi= th the exceptions you mentioned in a previous email about using some of tha= t space). The LSI-11 board has 4kW of RAM on it, and I have already a 16KW = board. If I want to further expand the RAM, and say I buy another 16kW boar= d, that makes an arithmetic sum of 32kW for the boards, making 36kW total. = Can the 4kW of on-board RAM be disabled, and only the 32kW on the boards be= used? Is it ok for the installed RA mto overlap the 8kW at the high memory= area? Do the devices spoof these addresses or do they read/write in the hi= gh installed RAM area?
