Compact Flash storage upgrade for a DECpc 433 -

Описание: Join me for a #DOSCember journey. Watch me make just about every conceivable mistake upgrading this ca. 1994 486sx laptop to a compact flash hard drive. I mean - you'd think I'd never worked on a DOS PC before! sheesh

I replace the original Seagate 2.5" IDE HDD with a 512MB CF card by cloning the original drive... eventually, anyway. Along the way, look at hard drive addressing, and the anatomy of an MS-DOS boot volume. Oh, and batteries.

1:42 - Disassembly
5:40 - USB-to-IDE adapter
6:36 - IDE HDD addressing modes
7:21 - Enter the Gateway
8:41 - Snag 2: HDD adapter boogaloo
9:33 - Clonezilla vs. Dosra
12:57 - Laptop CF card installation
13:48 - I swear a little (Snag 3)
14:48 - Let's try this again
16:06 - Snag 4
16:32 - Copy that floppy
18:53 - Five is Right Out!
20:34 - Size matters
22:10 - Nuke it from orbit
24:03 - MS-DOS boot process
25:23 - Qapla'!

Corrections:
The AST Bravo NB was available in the 33MHz speed.
