Windows 95 In Your Web Browser
|
|
---
|
|
|
|
Today, the last serious bug preventing a successful boot of Windows 95 was fixed. I won't bore you with
|
|
the details.
|
|
|
|
OK, I will: three arithmetic instructions (specifically, **AND**, **OR** and **XOR**) include a variation that
|
|
converts an immediate signed byte into a signed word. Those variations were failing to truncate the result when
|
|
a 16-bit operand size was in effect, and if the destination was a register, the upper 16 bits of that register
|
|
could become corrupted.
|
|
|
|
The [Windows 95 Test Machine](/devices/pc/machine/compaq/deskpro386/vga/4096kb/) hard disk has been updated
|
|
with a complete set of Windows 95 files from a "Compact" installation, and first boot has finished, so instead
|
|
of the initial "Getting ready to run Windows 95 for the first time..." splash screen, you'll see the normal
|
|
Windows 95 startup screen.
|
|
|
|
The machine is still a bit finicky. It easily gets confused about the state of its shift keys if you switch away
|
|
from the browser and then back again. And Explorer windows don't open in the correct view; for example, both
|
|
**My Computer** and **Recycle Bin** open the same (incorrect) view. In short, there are still some serious bugs
|
|
to be resolved, but booting has been achieved.
|
|
|
|
The adventure continues.
