I don't get those beeps for the 16-bit Cirrus card I've been using.Are your motherboard switches set correctly for EGA/VGA? On my 1986 XT, VGA will work fine without the switches set correctly, but you get the beeps for no video, even though the ROM gets initialized.
Although I am getting two long beeps before the video lights up and the POST RAM test starts.

Assumption: Your IBM XT (IBM 5160) motherboard's BIOS ROM's were no swapped out for third-party ones.Yes, I do have POST cards, but as far as I know, XT 5160 doesn't issue those checkpoints.
The BIOS author can do pretty much what they want to.Do VGA BIOSes do that?
Assumption: Your IBM XT (IBM 5160) motherboard's BIOS ROM's were no swapped out for third-party ones.
According to my reading of the BIOS source listings for the IBM 5160 motherboard, that BIOS does not issue two long beeps. If I had seen '2 long beeps' in the source code, I would have listed 'two long beeps' at [here].
The BIOS author can do pretty much what they want to.
For example, we know that the BIOS on an IBM EGA card will issue {1 long beep then 3 short beeps} if the card's BIOS discovers some cases of faulty video RAM.
Rhetorical: Could it be that the two long beeps is your VGA card informing you that it discovered a problem during its self-test? Does the card do that when it is in a different computer?
But... with that VGA card in the system the XT-CF-Lite is flaky. Sometimes doesn't display the correct ID string for the CF card.
With other VGA cards, I've never seen that symptom before.
Background: At the high level, the XT-CF-Lite hardware looks like [here].What address is the XT-IDE set for? There are some VGA cards that might conflict with C800, according to this: https://minuszerodegrees.net/xtide/XT-IDE - Basics.htm
I think Jafir mentioned that in case your XT-CF-Lite had been configured to start its ROM at C8000.The VGA ROM is at C0000 (and doesn't extend beyond and affect the MFM disk controller at C8000 when I checked it on the XT 5160).
340 is uncommon for an XT-IDE/XT-CF card. The vast majority of those cards default to 300. Perhaps try 300.XT-CF-Lite is set for D0000 and 340h.
