How can I change the drive letter?
As with any PM only drive - in Device Manager made it Removable, set letter, made it non Removable. And as drive can stopped and started in Device Manager - no reboot needed (if no swap file on this drive, of course).

You have to know already that I'am running one of my Windows 98 SE on Core i7 10700...

There is no problem for compatibility for pure protected mode software. The problem of RLoew's solution is transition from real mode code that drives something to protected mode code that access memory and back.

ramdrv4m - Universal RAM Drive for Windows 9x
https://github.com/LordOfMice/Tools/blob/master/ramdrv4m.zip
Features description:
1. Memory support above 4GiB (default mode).
Primary purpose of creating this software.
2. A full-fledged 32-bit protected mode driver.
3. High speed of operation.
4. Can utilize RAM Drives created in memory
by other software. In particular, it is compatible with
RAMDSK32/64 from RLoew.
5. It consumes only 4MiB of virtual address space.
In addition to the real memory used for RAM Drive itself, of course.
6. Works on Pentium and higher class processors
(i.e. it does not work on 80486).As usual - readme is your best friend...

Win9x VCACHE Protection Error Fix (.VXD version of CREGFIX.COM), primarily for Windows ME

I tested it on Windows 98SE so IDK if it actually works on Windows ME.

For clarity, let's say if we take a computer based on 440BX or similar, fully 9x compatible, does this recording succeed there?
Yes. With this flag cleared kernel mode code is ignoring the fact that page is read-only and writes on this page successfully.

IBM specifically tells the user to install 98SE without ACPI
Ok, may be in some cases (not my case, NForce2 PCs work with ACPI flawlessly). But in any case "without ACPI" and "setup /i" are NOT the same things.

It is highly recommended (outside of VirtualBox I think) to use "setup /p i" rather than "setup /p j" regardless of how old or new the PC is.
Why so? The PCs from 98-ME era are supported ACPI that is working in 98-ME, eh.

is it possible to somehow configure or replace the ACPI Table even before Windows starts
It is possible before and (much easy to do) WHEN Windows starts. ACPI driver in Win98 supports overriding of ACPI tables through the Registry.

1. mercury did the patch to win.com to run additional software on exiting from Windows which in turn can power off PC
2. without any patch you can do the same thing just running above mentioned software in MS-DOS Mode
n.b. - both questions are offtopic for this thread
p.s. I edited my previous post

if i use an external disk 500GB's the Explorer is rebooted
1. Try to access drive from other file manager - far, total comander or else.
2. Is this drive accessible on the same PC from other OS like XP?
5 hours ago, awkduck said:I don't know that you need it for USB.
RLoew did 64-bit LBA patch for SCSI and I wrote driver for the same (USB drives are SCSI from protocol view point), but 500GB drive has to use 32-bit LBA and does not need any patch by default.

First check that CD-ROM drive is present in Device Manager after reboot (better in hardrware tree view mode, of course).

>but one of our readers finally pointed out that Microsoft did provide a "partial description of the meaning [of these bytes] in KB article 192606 (or the file: MBtFAQ)."
JFYI, I am this reader
And I know slightly more, of course - the real IOS structure that used for passing these values (signatures and checksums).
>Can you detail which cases?
Excerpt from your link:
>or the first word after the boot code is non-zero, IOS will instead store a checksum of the MBR and the INT 13h unit number, rather than the MBR signature.
And as checksum include NT Disk Signature too -> we have unique value of this checksum.
>But during setup?
I don't see how this can affect setup too (as you), but NT Disk Signature has some impact on Windows 9x.
P.S. And what it looks like in reality (with MBR code from NT):
int13 = 80h, signature = E6FFB000h, checksum = F601BDECh, flags = 0001h
int13 = 81h, signature = E6FFB000h, checksum = BDE79504h, flags = 0001h
int13 = 82h, signature = E6FFB000h, checksum = E6233B84h, flags = 0001hWin9x signatures are equal, but checksums are different (and IOS is using checksums (flags = 0001h))

In some cases it is definitely used even on 9x. Not directly but in checksum of zero (MBR) sector.
