Re: [colorforth] Hello - and where to begin?

[Nick Maroudas <alice@xxxxxxxxxxxxxxxxxxxxxxx>]

Nick again:  Have succeeded to prepare a bootable
floppy
from Howerd's CFDOS4.blk image, for a 3GHz 64bit
Pentium
D on Intel 945 motherboard.  Having deduced that
previous difficulty might be a hardware problem (see
quote below) the solution was to prepare the floppy on
the same 64 bit PC that it is intended to boot. 
(Previously the floppy had been prepared with 0.5GHz
Pentium on 32 bit ASUS P2 board). Presumably this
reduces r/w errors due to electrical jitter.  Thanks,
Howerd, now I have a much faster CF01 - and on a PC that
doesn't even have an operating system, only BIOS.  

Q: Would CFDOS4 still work if one were to replace
blocks
1 to 18 (the CF01 core) with 18 blocks from Josh's CFO5
version (the one that uses 16bit color as CFO1 does)? 

Caritas,

NickM

booting native CF01.  Now I find the same applies to
booting from DOS.  No disrespect to Howerd ...
